Which MCP Server Should You Choose?
Choose Claude Task Master when:
You need dedicated capabilities in the Developer Tools domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (BYOK (Pay Provider Direct)).
You have access to required keys: ANTHROPIC_API_KEY, OPENAI_API_KEY, GOOGLE_API_KEY, PERPLEXITY_API_KEY, XAI_API_KEY, OPENROUTER_API_KEY, MISTRAL_API_KEY, TASK_MASTER_TOOLS.
AI-powered task management system for AI-driven development. Features PRD parsing, task expansion, multi-provider support (Claude, OpenAI, Gemini, Perplexity, xAI), and selective tool loading for optimized context usage.
MCP server exposing 11 honesty-SDK kits (grounding, trust, audit, corroboration) as agent tools.
Checks citation structure in AI-generated text, sentence by sentence: uncited claims, honest placeholders, and citations whose marker is missing or whose evidence doesn't match lexically. Structural only; it does not verify that the evidence is true. The word-overlap matcher rejects some faithful p…
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).
Claude Task Master is categorized under Developer Tools and uses a local stdio subprocess. In contrast, Honesty MCP belongs to Developer Tools using local stdio subprocess. Select Claude Task Master when you need capabilities focused on developer tools and Honesty MCP when you require tools for developer tools.
Reports the evidence direction (supports / contradicts / mixed / none) and a graded verdict from distinct sources, not a vote count. With corroboration-kit 0.3 and later, sources count by independent origin (pages of one site count once unless you declare an `origin`). Independence is not verified,…
check_payout_invariance
Checks, for the scenarios you supply, whether a ranking engine's output changes with who pays more (`runtime` mode, off unless `HONESTY_MCP_ENABLE_CODE_EXEC=1`) or whether payout identifiers appear in source text you send (`static-imports` mode, always available; it never reads files from disk). St…
check_mutation_invariance
Off unless `HONESTY_MCP_ENABLE_CODE_EXEC=1` (it is not listed otherwise). Checks, for the scenarios you supply, whether a decision/score/ranking function's output depends on a variable it claims not to (protected attribute, geography, price, or anything you name). Not a formal proof for every possi…
score_trust_identified
Scores an entity from known, identified contributors (reviewer accounts, raters, inspectors), shrinking thin evidence toward a prior. With no weighted evidence it returns the prior with `insufficient` confidence, not a measured score.
assess_anonymous_authenticity
Scores unattributed/scraped sentiment on how organic it looks, with a heuristic discount for two specific patterns (source concentration, unusually uniform sentiment). It does not detect fabrication or verify independence, it is not a sentiment ranking (a strongly negative corpus scores lower than…
check_provenance_claims
Flags certainty-implying language ("(verified)", "guaranteed") not backed by an appropriate provenance tier. The default phrase list is short (eleven phrases) and phrases match as word prefixes.
check_claims_registry
Buckets public-facing claims as current / stale / unverified against their linked evidence and last-verified date. With claims-registry-kit 0.4 and later, a placeholder reference such as `TODO` is unverified and the age limit is exact to the millisecond.
append_audit_entry
Appends one entry to a hash-chained, tamper-evident audit log.
verify_audit_chain
Independently re-verifies a hash chain from genesis (an empty chain is valid with nothing checked); detects mutation and severed links unconditionally, plain tail deletion with `expectedMinLength`, and truncate-and-re-append (or a full rewrite) only with `anchor`; `expectedMinLength` alone does NOT…
grade_decision
Grades one recommendation-and-decision pair against a before/after observation log, exposure-aligned, with separate floors per window and machine-readable refusal codes. `holding` requires both the exposed bad count to stay under `refuteThreshold` AND its bad rate to be below the baseline's (exact…
compute_divergence
Measures how often an engine and a human disagreed, and where a later outcome exists, reports engine-right/human-right as separate, never-blended counts. The optional custom `groupBySource` input is off unless `HONESTY_MCP_ENABLE_CODE_EXEC=1`.
