Tools & Capabilities Breakdown
Depscope Tools (22)
check_malicious
Supply-chain malware check against OpenSSF/OSV. USE WHEN: about to suggest install of an unvetted/unfamiliar package; name came from a blog/tutorial. Call BEFORE check_package for untrusted pkgs. RETURNS: {is_malicious, threat_tier, source}.
check_typosquat
Typosquat detector. USE WHEN: name differs from a well-known package by 1-2 chars (`lodsh`, `reqeusts`); copy-paste from unreliable source; downloads near zero but name looks familiar. RETURNS: {is_typosquat, likely_target, confidence}.
check_bulk
Fast pre-flight filter for a batch of (ecosystem, package) pairs. DB-only, <100ms for 100 items. USE WHEN: about to emit `npm install a b c …` or `pip install a b c …` — catches hallucinated names, stdlib, typos, and known-bad in ONE call. NOT a dep-tree audit (use scan_project for that). RETURNS: per-item {status: exists|stdlib|malicious|typosquat_suspect|historical_incident|unknown}.
package_exists
Boolean registry existence check. USE WHEN: about to emit a package name in an install command but unsure it exists; verifying a name generated from training data. RETURNS: {exists}.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Depscope is categorized under Security and uses a local stdio subprocess. In contrast, Swagger Testcase MCP belongs to Security using local stdio subprocess. Select Depscope when you need capabilities focused on security and Swagger Testcase MCP when you require tools for security.
Latest published version + deprecation flag — the cheapest call. USE WHEN: only a version string matters (pinning a dep, answering 'what version of X'). If you also need health/vulns use check_package. RETURNS: {latest, deprecated, published_at}.
get_health_score
Single 0-100 health score — cheapest go/no-go gate (>=70 safe). USE WHEN: CI gating or pkg already screened for malware/typos. NOT a first screen — run check_malicious + check_typosquat first. For a verbal verdict use get_package_prompt. RETURNS: {score, verdict}.
install_command
Canonical install command(s) across every package manager of the ecosystem (npm/pnpm/yarn/bun, pip/uv/poetry, cargo, go, composer, maven+gradle, nuget, …). USE WHEN: emitting an install line and you want correct flags. RETURNS: {primary, variants[]}.
get_package_prompt
LLM-optimised package brief — plain text ~300 tokens (~75% cheaper than JSON). Verdict (SAFE/AVOID/URGENT/MALICIOUS) + health + vulns + alternatives + maintainer alerts. USE WHEN: you want to reason over a package and drop the output directly in context; 'is X safe'. PREFER THIS over check_package in 95% of LLM cases. RETURNS: plain-text brief.
check_package
Full machine-readable JSON report (~2k tokens). USE WHEN: you need to programmatically parse specific fields (CI gating, UI, sub-field extraction). Otherwise prefer get_package_prompt. RETURNS: {package, health:{score}, vulnerabilities[], latest, deprecated, maintainers, recommendation}.
get_vulnerabilities
CVE/OSV advisories affecting the latest (or specified) version. USE WHEN: security-sensitive project; user asks 'any CVEs in X'; you already know the pkg exists. RETURNS: {vulnerability_count, vulnerabilities[]: {id, severity, cvss, fixed_in}}.
find_alternatives
Curated replacements for deprecated/unhealthy packages, including stdlib built-ins (e.g. `fs.rm` for rimraf). USE WHEN: pkg flagged AVOID/URGENT; 'what to use instead of X'; before guessing a replacement name. RETURNS: {alternatives[]: {name, reason, is_stdlib}}.
get_migration_path
Prescriptive migration plan between DIFFERENT packages — rationale + literal code diff + breaking changes + effort minutes. USE WHEN: replacing `request`→`axios`, `moment`→`dayjs`, `flask`→`fastapi`, etc.; both endpoints known. RETURNS: {rationale, diff, breaking_changes[], estimated_minutes}.

Swagger Testcase MCP Tools (10)
fetch_swagger
Fetch and parse an OpenAPI/Swagger specification. Supports:
- Public URLs: https://api.example.com/swagger.json
- Internal URLs (accessible from user's machine/VPN): https://internal-api.company.com/docs/swagger.json
- Local files: /path/to/swagger.json, ./api-spec.yaml
- Auth-protected specs: pass auth_header for Bearer/Basic/API-Key auth
analyze_endpoint
Analyze a specific endpoint from a loaded Swagger spec. Returns detailed info about parameters, request body, responses, and security.
generate_test_cases
Generate QA test cases for a specific API endpoint. Produces positive, negative, boundary, auth, security, idempotency, pagination, and business logic test cases based on the OpenAPI spec.
generate_test_cases_batch
Generate QA test cases for multiple endpoints at once. Optionally filter by tag, methods, or path prefix.
export_test_cases
Export previously generated test cases in various formats: markdown, json, csv, allure_csv, gherkin, postman, k6, pytest, testrail_csv (Steps template), testrail_csv_text (Text template).
compare_specs
Compare two versions of an OpenAPI spec. Detects added/removed/modified endpoints, schema changes, and breaking changes.
validate_spec
Validate an OpenAPI spec for quality and completeness. Checks for missing descriptions, orphaned schemas, naming inconsistencies, missing error responses, and more. Returns a quality score (0-100).
generate_mock_data
Generate realistic mock/sample data from an endpoint's request or response schema. Useful for populating Postman, tests, or documentation.
suggest_missing_tests
Analyze test coverage for generated test cases. Shows which response codes, parameters, and boundary conditions are covered or missing. Provides prioritized suggestions for additional tests.
clear_cache
Clear cached specs and/or generated test cases. Useful when the spec has been updated and needs to be reloaded.
