SUMMARY

MCP server for Open Knowledge Format (OKF) bundles — okf-ingest's deterministic consume verbs (context, search, impact, diff, doctor) as agent tools

README.md

okf-mcp

MCP server for Open Knowledge Format bundles — expose okf-ingest's deterministic consume verbs as tools any MCP client (Claude Code, Cursor, custom agents) can call.

Existing OKF MCP servers hand agents the markdown files. This one hands them
the queryable catalog and concept graph: index-first context assembly,
impact/backlink analysis, SQL over frontmatter, drift diffs, and health checks —
all deterministic okf-ingest code, no model calls in the server.

Tools

Tool What the agent gets
okf_list_bundles which bundles this server exposes
okf_search concepts whose title/body match a term
okf_get_concept one concept's frontmatter + full body
okf_context the flagship — index.md + a concept's most relevant neighborhood as one curated markdown blob, ranked by exact Personalized PageRank over the author's link graph (pass rank='bfs' for plain depth) — or pass query (a free-text question) instead of start for lexical-seeded multi-PPR retrieval
okf_related the k concepts most relevant to a topic — exact PPR, no embeddings
okf_impact inbound / outbound / transitive links — "what breaks if X changes"
okf_sql read-only SELECT over the DuckDB catalog (okf_concept, okf_link, okf_validation)
okf_diff what changed on disk since the server loaded the bundle — an agent's memory-refresh between looks
okf_refresh re-ingest a directory bundle after okf_diff shows changes
okf_doctor health score + per-rule findings before trusting a bundle

Install & run

pip install okf-mcp        # depends on okf-ingest >= 0.9.0

# one or more bundles: directories and/or okf-ingest .duckdb catalogs,
# optionally named (first one is the default target)
okf-mcp ~/my-bundle
okf-mcp wiki=~/wiki notes=~/vault snapshot=./kb.duckdb

Register with Claude Code:

claude mcp add okf -- okf-mcp ~/my-bundle

Or in any MCP client config:

{ "mcpServers": { "okf": { "command": "okf-mcp", "args": ["wiki=/path/to/bundle"] } } }

Design notes

  • Read-only. Directory bundles are ingested into disposable in-memory
    DuckDB catalogs at startup; .duckdb sources open read-only; okf_sql
    accepts SELECT/WITH only. The server never writes to your bundle.
  • Deterministic. Every tool is plain okf-ingest code — same input, same
    answer; the only nondeterminism an agent sees is its own.
  • Concepts resolve by name. okf_get_concept / okf_context / okf_impact
    accept a path or a wikilink-style name — id, alias, title, or filename stem,
    compared on alphanumerics ('agent memory architecture' finds
    ops/agent_memory_architecture.md). Ambiguous names return the candidate
    list instead of guessing.
  • [[wikilinks]] work. Vault-style bundles (Obsidian/Logseq/Foam) resolve
    by id / alias / title / stem, same as okf-ingest 0.6.0+.

Apache-2.0. Sibling project: okf-ingest (the R + Python ingestion tool this wraps).
