Which MCP Server Should You Choose?
F
Choose Fact Check when:
You need dedicated capabilities in the Developer Tools domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
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.
verify_claim
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
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).
Fact Check is categorized under Developer Tools and uses a local stdio subprocess. In contrast, Codealive MCP belongs to Developer Tools using local stdio subprocess. Select Fact Check when you need capabilities focused on developer tools and Codealive MCP when you require tools for developer tools.
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.
