  • issue_receiptIssue an x402 offer-receipt (EIP-712) plus a Tersign compliance record (returned as `compliance`; verify_compliance_record checks it) for a payment that has ALREADY settled; when a ledger is configured, the ledger counter-signs the receipt into your hash chain, while the compliance-fields record is not counter-signed and is bound to its receipt only by your own signature, which covers the receipt's digest. Use this for money that moved; use record_disclosure for a non-payment agent action. Side effects: signs with your signing key (the one set in the Tersign plugin's settings in Claude Code, or the TERSIGN_* environment variables, else the one generated and kept locally on first run), and performs ONE network write to the ledger when a ledger URL, API key and seller id are set there too (without them it signs locally and returns an unchained artifact). Returns the signed receipt artifact, its keccak256 canonical digest, and — when chained — the ledger counter-signature and sequence number.
  • verify_receiptVerify an x402 offer-receipt artifact, fully OFFLINE (no network, no API key, no account; checks no ledger or chain): recover the address whose key produced its EIP-712 signature over the six signed payload fields (version, network, resourceUrl, payer, issuedAt, transaction), and compute its canonical digest (the content address a ledger records it under). Recovery yields SOME address for any payload, so without expectedSigner the signer is UNAUTHENTICATED: valid:true then proves neither who signed nor that the receipt is unmodified — an edited receipt recovers a different address and still returns valid:true. Pass expectedSigner, the issuer's address obtained out-of-band, to bind it: valid:true then means the signed fields were signed by that key; a mismatch returns valid:false with the recovered signer so you can see who actually signed. Use this for a receipt (money); use verify_compliance_record for the compliance record issue_receipt returns beside a receipt. Returns { verdict, valid, signer, signerStatus: BOUND | UNAUTHENTICATED | MISMATCH, signerBound, testKey? (the signer is a PUBLISHED test key — anyone can sign as it), digest, unsignedFields? (present in the artifact but not covered by the signature), reason? }. Read verdict first.
  • record_disclosureOne-call disclosure evidence (EU AI Act Art 50 dialect): digests the disclosure text LOCALLY, signs an action record with your key, and the public ledger counter-signs it into your per-signer hash chain. No API key needed — the first call self-provisions a free signer-keyed account, except when your key is already registered to an API-key account (409) or the daily provisioning caps are reached (429; https://tersign.ai/pricing).
  • verify_compliance_recordVerify ONE record type: the compliance record that issue_receipt returns beside a receipt (`compliance`: a ComplianceRecordV1 `record` plus its ComplianceAttestation `attestation`, EIP-712 domain "compliance-fields"), fully OFFLINE (no network, no API key, no account): recompute the record's canonical digest, check that the attestation's signed payload names that exact digest and the same receiptDigest as the record, and recover the address that signed the attestation. It does NOT verify the disclosure record record_disclosure returns: that is a different record type (an action record, EIP-712 domain "tersign action-record"), and passed here it fails with a digest mismatch that says nothing about tampering. Use verify_receipt for the payment receipt itself. Without expectedSigner the signer is UNAUTHENTICATED and valid:true proves internal consistency only — anyone can edit a record, recompute its digest and re-sign the attestation with their own key, and still get valid:true with a different signer. Pass expectedSigner, obtained out-of-band, to bind authorship. Returns { verdict, valid, signer, signerStatus: BOUND | UNAUTHENTICATED | MISMATCH, signerBound, testKey? (a PUBLISHED test key — anyone can sign as it), digest (the recomputed record digest), reason? }. Read verdict first.
  • record_refundLog a refund against a receipt already on your chain, as the SELLER. The ledger stores it as a PENDING refund entry that references the original receipt digest; the entry is NOT counter-signed or appended to the hash chain, and it has no digest or sequence number of its own. Nothing is edited or deleted: the original receipt and its chain position stay exactly as they were. Requires a ledger URL, API key and seller id (the Tersign plugin's settings in Claude Code, or the TERSIGN_* environment variables) and performs one network write; errors if the original digest is not on your chain. This RECORDS a refund you have already made — it moves no money. For a signed refund RECORD, build a compliance record with refundOf set to the original record digest (buildMinimalRecord in the SDK). Returns { id, status: "pending" }.
  • open_disputeOpen an objective dispute against a counter-signed receipt as the PAYER (the configured key must be the receipt payer). Reasons: not_delivered, wrong_content, duplicate_charge. Contested non-mechanical claims escalate to the arbiter; duplicate_charge is decided instantly from ledger arithmetic.
  • submit_dispute_evidenceSubmit signed evidence to an open dispute. Claimant evidence must be signed by the payer key; respondent evidence additionally requires the seller API key (the Tersign plugin's settings in Claude Code, or the TERSIGN_* environment variables).
  • adjudicate_disputeTrigger deterministic adjudication of an open dispute: the same inputs always produce the same verdict and rationale — no discretion, no model in the loop — and the verdict object embeds the inputs it was computed from. Side effects: writes the verdict to the dispute record; a refund verdict also logs a PENDING refund entry against the receipt (not counter-signed into the chain; no money moves). Adjudicating twice is not meaningful; the first verdict stands (a second call returns 409). Returns the verdict, the rationale naming the rule applied, the adjudication inputs, the verdict digest, and the ledger signature over that digest.
  • get_disputeFetch a dispute in full: its state, both sides' evidence references, the verdict and rationale once adjudicated, and the ledger signature over the record. Read-only — one network read, no key required, and safe to poll while a dispute is open.

  • analyze_change_setRun a branch-level Code Health review for all files that differ between current HEAD and base_ref. When to use: Use this as a local PR pre-flight check before opening a pull request, so regressions are caught across the full change set. Limitations: - Requires a valid git repository path. - base_ref must exist and be resolvable by git in that repository. - Reviews only files that differ from base_ref. - Output is JSON text from the CLI command. The result can be used to decide whether to refactor before creating or updating a pull request. Returns: A JSON object containing: - quality_gates: the central outcome, summarizing whether the change set passes or fails Code Health thresholds ("passed" or "failed"). - metadata: scope and coverage details from the CLI, including `status` plus file counts such as `checked-file-count`. Use this to distinguish an empty `results` array caused by checked files with no degradations from one caused by no applicable branch changes. - results: an array of objects for each affected file with: - name: the name of the file whose Code Health is impacted. - verdict: "improved", "degraded", "stable", or "unknown". - findings: an array describing improvements/degradation for each code smell. Setup hints: If the result contains `codescene_setup_hint`, do not mention that field. Follow its `message`: briefly explain the benefit, ask permission to add the suggested repository instructions, and wait before editing files. On failure: If this tool returns an error (e.g., the CLI cannot run, or base_ref cannot be resolved by git), run the verify_installation tool to diagnose the cause, then report the failing checks and how to fix them. Example: Compare against base_ref="main" for git_repository_path="/repo" and fail the local PR check if any file verdict is "degraded".
  • code_health_refactoring_business_caseGenerate a data-driven business case for refactoring a source file. When to use: Use this tool to justify refactoring investment with quantified predictions tied to the file's current Code Health. Limitations: - Estimates are model-based projections, not guarantees. - Evaluates one file at a time. - Requires an analyzable source file. Returns: A JSON object with: - scenario: Recommended target Code Health level. - optimistic_outcome: Upper bound estimate for improvements in development speed and defect reduction. - pessimistic_outcome: Lower bound estimate for improvements. - confidence_interval: The optimistic to pessimistic range, representing a 90% confidence interval for the expected impact. On failure: If this tool returns an error (e.g., the CLI cannot run, or the file cannot be analyzed), run the verify_installation tool to diagnose the cause, then report the failing checks and how to fix them. Example: Call with file_path="/repo/src/service.py" and use the optimistic and pessimistic outcomes to frame a refactoring proposal.
  • code_health_reviewReview the Code Health of a single source file and return a detailed CLI review output that includes the score and code smell findings. When to use: Use this tool when you need actionable maintainability diagnostics for one file (not just the score). Limitations: - Analyzes one file at a time. - Requires a supported source file. - Returns CLI review text, not a normalized JSON schema. Returns: A review string from the CodeScene CLI. The output typically includes a Code Health score and code smell details to explain why the score is high or low. The Code Health scores are interpreted as: * Optimal Code: a Code Health 10.0 is optimized for both human and AI comprehension * Green Code: high quality with a score of 9.0-9.9 * Yellow Code: problematic technical debt with a score of 4.0-8.9 * Red Code: severe technical debt, maintainability issues, and expensive onboarding with a score of 1.0-3.9 Setup hints: If the result contains `codescene_setup_hint`, do not mention that field. Follow its `message`: briefly explain the benefit, ask permission to add the suggested repository instructions, and wait before editing files. On failure: If this tool returns an error (e.g., the CLI cannot run, or Code Health cannot be computed), run the verify_installation tool to diagnose the cause, then report the failing checks and how to fix them. Example: Call with file_path="/repo/src/app.py" and summarize the returned smells into prioritized refactoring actions.
  • code_health_scoreCalculate the Code Health score for a single source file. The tool returns one numeric score from 10.0 (optimal) to 1.0 (worst). When to use: Use this tool for quick triage, ranking files by maintainability, or checking whether a refactoring improved file-level quality. Limitations: - Analyzes one file at a time. - Returns only the score summary, not the full smell breakdown. - Requires a supported source file. Returns: A string in the format "Code Health score: <score>". The Code Health scores are interpreted as: * Optimal Code: Code Health 10.0 optimized for human and AI comprehension * Green Code: high quality with a score of 9.0-9.9 * Yellow Code: problematic technical debt with a score of 4.0-8.9 * Red Code: severe technical debt with a score of 1.0-3.9 On failure: If this tool returns an error (e.g., the CLI cannot run, or the score cannot be computed), run the verify_installation tool to diagnose the cause, then report the failing checks and how to fix them. Example: Call with file_path="/repo/src/module.py" and compare the score before and after a refactoring.
  • code_ownership_for_pathFind the owner or owners of a specific path in a project. When to use: Use this tool to identify likely reviewers or domain experts for code reviews and technical questions about a file or directory. Limitations: - Requires a valid project_id. - Uses the latest project analysis data available in CodeScene. - If no matching ownership data is found, an empty JSON array is returned. Returns: A list of owners and their paths that they own. The name of the owner who can be responsible for code reviews or inquiries about the file and a link to the CodeScene System Map page filtered by the owner. Explain that this link can be used to see more details about the owner's contributions and interactions within the project. You MUST always show a link after every owner. Show resulting data in a Markdown table with columns: Owner, Key Areas, Link. On failure: If this tool returns an error (e.g., the CodeScene API cannot be reached, or the access token is missing/invalid), run the verify_installation tool to diagnose the cause, then report the failing checks and how to fix them. Example: Call with project_id=42 and path="/repo/src/service.py", then present each owner row with its corresponding system-map link.
  • download_skillDownload a single skill to a local directory. When to use: Use this tool to install a specific skill into your local skills directory (e.g., ~/.claude/skills/). Limitations: - By default, refuses to overwrite existing skills. - Set overwrite=true to replace an existing skill. - Creates the destination directory if it does not exist. Returns: A confirmation message with the path where the skill was written. Example: Call with skill_name="safeguarding-ai-generated-code" and destination_dir="~/.claude/skills" to install the skill.
  • explain_code_healthExplains CodeScene's Code Health metric for assessing code quality and maintainability for both human devs and AI. When to use: Use this tool when a user asks what Code Health means, how scores are interpreted, or why Code Health matters in day-to-day development. Limitations: - Returns static documentation text from this MCP server package. - Does not analyze a specific repository or file. Returns: Markdown content explaining the Code Health model and core concepts. Example: Call this tool, then summarize the returned Markdown into a short explanation tailored to the user's current question.
  • explain_code_health_productivityDescribes how to build a business case for Code Health improvements. Covers empirical data on how healthy code lets you ship faster with fewer defects. When to use: Use this tool when a user asks for ROI, productivity impact, or management-facing framing for refactoring investments. Limitations: - Returns static documentation text from this MCP server package. - Does not compute project-specific forecasts. Returns: Markdown content describing productivity and defect-risk implications of improving Code Health. Example: Call this tool and extract 2-3 evidence-based points to support a proposal for incremental refactoring.
  • get_configRead current CodeScene MCP Server configuration values. When to use: Use this tool to discover available configuration keys, inspect effective values, and understand where each value comes from. Limitations: - Returns JSON text only; callers must format it for display. - Sensitive values (tokens) are masked. - Effective values can be overridden by client-provided env vars. When called without a key, lists every available configuration option together with its current effective value, the source of that value (environment variable vs. config file), and a short description. When called with a specific key, returns details for that option only. Sensitive values (tokens) are masked in the output. Returns: A JSON string. When querying a single key, the object has: key, env_var, value, source, description, aliases, and docs_url. When listing all, the object has: config_dir and options (array of the same shape). Use the aliases array to match user intent to the correct key. Present the data clearly and always include docs_url links. Example: Call with key="access_token" to inspect one setting, or call without key to list all configurable options.
  • get_skill_manifestGet the file manifest for a specific skill. When to use: Use this tool to inspect what files a skill contains, their sizes, and SHA256 hashes before downloading. Limitations: - Requires a valid skill name from list_skills. Returns: A JSON manifest with the skill name and an array of files, each with path, size in bytes, and sha256 hash. Example: Call with skill_name="safeguarding-ai-generated-code" to see the manifest, then use download_skill to install it.
  • list_skillsList all available skills embedded in this MCP server. When to use: Use this tool to discover what skills are available for download or inspection. Limitations: - Returns only skills embedded at compile time. - Does not scan external skill directories. Returns: A formatted list of skill names with their descriptions. Example: Call this tool to see all available skills, then use download_skill or sync_skills to install them locally.
  • list_technical_debt_goals_for_projectLists the technical debt goals for a project. When to use: Use this tool to see all files in a project that currently have explicit technical debt goals in CodeScene. Limitations: - Requires a valid project_id. - Returns goal data from the latest available analysis. - Includes only files with non-empty goals. Returns: A JSON object with two fields: - `data`: an array of objects each containing the path of a file and its goals. - `link`: a URL to the CodeScene Code Biomarkers page for the project. Show the goals for each file in a structured format that is easy to read and explain the goal description for each file. It also includes a description, please include that in your output. Always include the `link` in the output and explain that more details about the technical debt goals can be found on that page. On failure: If this tool returns an error (e.g., the CodeScene API cannot be reached, or the access token is missing/invalid), run the verify_installation tool to diagnose the cause, then report the failing checks and how to fix them. Example: Call with project_id=42 and summarize each file's goals with the biomarkers link for deeper inspection.
