Reasons Service

Domain knowledge bases powered by epistemic reasoning

Connecting Claude Code

The quickest way to add the MCP server:

claude mcp add reasons-service --transport streamable-http https://ftl.reasonsforge.com/mcp

Then authenticate:

claude mcp login reasons-service

Once connected, try asking Claude:

Prompt	What it does
`List domains`	Shows all available knowledge bases
`List beliefs for my-domain`	Browse beliefs in a knowledge base
`Find issues for my-domain`	Finds gated beliefs blocked by unless-list dependencies
`Explain belief-id in my-domain`	Traces the justification chain for why a belief is IN or OUT
`Deep search about security in my-domain`	IDF-ranked search across beliefs and source documents
`Search for authentication in my-domain`	Full-text search across beliefs, entries, and sources
`What would happen if we retracted belief-id in my-domain?`	Simulates the retraction cascade without modifying data
