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.
Fact-check claims against independent sources — fast verdict or deep multi-step investigation.
Fast verdict (~10s) via a 3-model panel. The default for checking a claim. Returns one verdict per atomic claim (True / Mostly True / Mixed / Mostly False / False) plus bucketed confidence.
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).

Select Claude Task Master when you need capabilities focused on developer tools and Fact Check when you require tools for developer tools.
Deep, multi-step investigation (~90s: research → debate → panel review) for high-stakes claims. Returns a `task_id` immediately; poll it with `get_verification`. Costs an order of magnitude more credits than `assess_claim` — reserve it. Pass `depth: "low"` for a shallower, faster research pass (few…
get_verification
Retrieve or poll a `verify_claim` result by `task_id`. Returns `processing`, `needs_input`, or `completed` (verdict, summary, top sources, and the `depth` the verdict was produced at).
select_claims
Resolve a `needs_input` verification — when a `verify_claim` turns up multiple claims or an ambiguity, pick which claim text(s) to run.
ask_followup
Ask a grounded follow-up about a completed `verify_claim` (by its `verification_id`) — answered from the full research, debate, and panel review, not just the summary. Costs credits at the cheap rate, same as `assess_claim`.
check_usage
Your remaining credits, the per-tool price list (`costs`, plus `cost_options` for prices that depend on a parameter such as `depth`), and your current plan.
