# fact.guide — Fact Synthesis & Verification MCP Server

> Model Context Protocol server for creating, verifying, and synthesizing
> atomic facts in a fractal verification graph with Capacitor integration.

## Tools Available
- fact_create: Create a new atomic fact (claim, observation, measurement, inference, or axiom) in the fact graph.
- fact_update: Update an existing fact node (state, text, type, etc.).
- fact_delete: Soft-delete a fact node.
- fact_graph: Get the complete fact graph for the current space, including nodes, links, and verification metrics.
- fact_search: Search for facts by text content or normalized claim.
- fact_decompose: Use LLM to decompose a compound statement into atomic, independently verifiable claims.
- fact_enrich: Use LLM to enrich a fact with normalized claim, suggested sources, and risk assessment.
- fact_round_create: Start a new commit-reveal verification round for a fact. Validators bond EDGEWORK tokens to participate.
- fact_round_commit: Submit a blinded commit (hash of vote + salt) to a verification round.
- fact_round_reveal: Reveal a previously committed vote with the salt and reasoning.
- fact_round_settle: Settle a verification round after the reveal phase, computing consensus.
- fact_round_dispute: File a dispute against a settled verification round within the dispute window.
- fact_rounds_list: List verification rounds, optionally filtered by phase or fact.
- fact_entropy: Get clarity and confidence metrics for the fact space.
- fact_anchor_status: Get Merkle batch anchoring status on Optimism L2.
- fact_anchor_trigger: Manually trigger a Merkle batch anchoring cycle.
- fact_reputation: Get the validator reputation leaderboard.
- fact_sync_pull: Pull new operations since a given clock for CRDT sync.
- fact_presence_heartbeat: Send a presence heartbeat to keep your peer visible in the space.
- fact_presence_list: List currently active peers in the fact space.
- fact_synthesize: Generate a full Capacitor synthesis for a fact, including Capacitor blocks, evidence chains, and verification status. Returns a structured synthesis document.
- fact_synthesize_batch: Batch-synthesize multiple facts into Capacitor documents. Returns an array of synthesis documents.
- fact_enrich_esi: Trigger ESI-powered LLM enrichment for a fact: normalizes the claim, generates analysis, suggests sources, and assesses risk. Optionally writes the results back to the fact graph.
- fact_build_enrichment_prompt: Preview the LLM prompt that would be used for ESI enrichment without executing it. Useful for debugging or customizing the enrichment pipeline.
- fact_capacitor_state: Get the current Capacitor state for a fact — blocks, projection, layout metadata. This is the data needed to render the fact via the Capacitor container.
- fact_capacitor_project: Switch the active projection surface for a fact — text, audio, spatial, or reading.
- fact_capacitor_blocks: Get the raw Capacitor blocks for a fact — the building blocks for layout solving.
- fact_build_evidence_chains: Analyze the fact graph to discover implicit evidence chains — links between claims, supporting observations, and conflicting inferences.
- fact_semantic_search: Search the fact graph using semantic similarity (embedding-based). Returns facts ranked by vector distance rather than keyword match.
- fact_flow_decompose: LLM-powered decomposition that breaks a compound claim into atomic sub-facts and creates them as children in the fact graph.
- fact_collab_start: Start a collaborative editing session for a fact via the Collab Durable Object. Returns a session key and connection details.
- fact_collab_join: Join an existing collaborative session. Returns the current session state and participant list.
- fact_render_claim_review: Generate a ClaimReview JSON-LD structured data object for a fact. Useful for SEO and fact-checking protocol compliance.
- fact_render_synthesis: Render a fact synthesis as a Markdown document suitable for display or export.
- fact_synthesize_with_esi: Synthesize a fact using the Aeon ESI processor pipeline. Uses the configured EdgeWorkersESIProcessor with KV caching, tier enforcement, and telemetry instead of raw inference calls.
- fact_memory_push: Push a fact-linked memory entry into a Fractal Memory stack.
- fact_memory_pop: Pop an entry from a Fractal Memory stack.
- fact_memory_peek: Peek the top of a Fractal Memory stack.
- fact_memory_pin: Pin a Fractal Memory entry.
- fact_memory_unpin: Unpin a Fractal Memory entry.
- fact_memory_get_pool: Read the Fractal Memory pool.
- fact_memory_get_recent: Read recent Fractal Memory entries.
- fact_memory_get_pinned: Read pinned Fractal Memory entries.
- fact_memory_get_feed: Read combined Fractal Memory feed.
- fact_memory_link: Create a Fractal Memory relation edge.
- fact_memory_get_related: Read Fractal Memory relations.
- fact_memory_join_collab_stack: Join a Fractal Memory collaborative stack.
- fact_memory_get_collab_stack: Read Fractal Memory collaborative stack snapshot.
- fact_memory_leave_collab_stack: Leave a Fractal Memory collaborative stack.
