Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00030 | $0.01755 |
| Opus 5 | $0.00015 | $0.00877 |
| Sonnet 5 | $0.00006 | $0.00351 |
| Haiku 4.5 | $0.00003 | $0.00176 |
Grade A, and why
setup scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Then: `curl http://127.0.0.1:8000/api/search?q=auth&limit=5`. How it starts
The opening of the file, as written. The whole thing — 277 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Setup
Gets you from nothing to "agent searching my docs" in 60 seconds.
Usage
/gnosis:setup # Interactive — asks where your docs live
/gnosis:setup /path/to/docs # Same, but ingest that folder right away
/gnosis:setup --postgres # Print PostgreSQL setup instructions too
Target: $ARGUMENTS
Step 1 — Install
Pick the extras you need. They're additive.
pip install gnosis-mcp # core (SQLite, keyword search)
pip install 'gnosis-mcp[embeddings]' # + local ONNX embeddings (hybrid search)
pip install 'gnosis-mcp[web]' # + web crawler (sitemap / BFS)
pip install 'gnosis-mcp[postgres]' # + PostgreSQL backend
pip install 'gnosis-mcp[rst,pdf]' # + .rst and .pdf file ingestion
pip install 'gnosis-mcp[reranking]' # + cross-encoder reranker
# (OFF by default; tune before turning on —
# the bundled MS-MARCO model can HURT
# dev-doc retrieval by ~27 nDCG@10)
Full stack in one shot:
pip install 'gnosis-mcp[embeddings,web,postgres,rst,pdf]'
Verify:
gnosis-mcp --version # should print the semver (≥ 0.10.13)
Step 2 — Pick a backend (usually SQLite)
SQLite (default): zero config. Database auto-creates at
~/.local/share/gnosis-mcp/docs.db. Great up to ~100 k chunks.
PostgreSQL: use when you have multiple concurrent writers, need a shared index across machines, or corpus > 100 k chunks.
# Postgres (only if you need it)
export GNOSIS_MCP_DATABASE_URL="postgresql://user:pass@localhost:5432/mydb"
Check that pgvector is available on the server:
psql "$GNOSIS_MCP_DATABASE_URL" -c "CREATE EXTENSION IF NOT EXISTS vector;"
Step 3 — Initialise the database
Idempotent. Safe to run any time.
gnosis-mcp init-db
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

setup is a skill published in the GitHub repository nicholasglazer/gnosis-mcp (29 stars, last pushed 16d ago), licensed MIT. It adds 30 tokens to every session and 1,755 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
