Sealtier MCP Server

sealtier

sealtier checks a folder of Markdown files against the Open Knowledge Format (OKF) v0.2 frontmatter tiers — Bronze, Silver, Gold — entirely on your own machine. It tells you which tier a knowledge base reaches, exactly which frontmatter fields each file is missing for the next tier, whether a document can still be trusted, and what a git edit did to that trust. It reads only: a scan writes nothing anywhere, and no tool in this package makes a network call.

It is a clean-room rebuild of the jidoseal-mcp server's three local tools. The original's two remaining tools are not rebuilt: one creates a paid Stripe Checkout session (a payment funnel), and the other's decisive output is a price that is published only on the vendor's website, so it cannot be reproduced from the public record.

What it checks

A field counts only if it has real content — title: with nothing after it earns nothing.

A corpus's tier is the tier of its weakest file. Coverage is the share of files reaching each tier. Each missing field is marked AUTO (a value the tool can propose) or NEEDS-CLIENT (only the owner can answer). The 0–100 score is round(mean of the three coverage values) — a reconstruction, disclosed as such: the original publishes a worked value (44 for coverage 66.7 / 33.3 / 33.3) but no formula, and this formula reproduces it. The Merkle root is the hex sha256 of the concatenated per-file sha256 hex digests, files ordered by name — also a disclosed reconstruction.

A note on egress: the original vendor claims its scan engine sends nothing over the network. That is the vendor's own claim about its proprietary engine, not independently audited. This rebuild is simpler to reason about: it imports no HTTP client and opens no socket, and jidoseal_changes starts exactly one program — the local git, with transports disabled (protocol.allow=never, GIT_NO_LAZY_FETCH=1).

One recorded deviation: the original also writes .jidoseal/manifest.json and .jidoseal/progress.ndjson under the scanned folder. This rebuild is read-only and writes nothing.

Install

npx @reneturcios/sealtier jidoseal_scan '{"path":"/path/to/notes"}'

Or run the container image:

docker run -i ghcr.io/cloudcorprecords/sealtier

The container defaults to the MCP server (see below). Pass CLI arguments to use it as a CLI instead.

CLI

Each command takes its arguments as one JSON object and prints the JSON result.

# Tier a folder of Markdown files
sealtier jidoseal_scan '{"path":"~/notes"}'

# Trust verdict for one file, or every *.md in a folder
sealtier jidoseal_trust '{"path":"~/notes/policies/leave.md"}'

# What changed since HEAD, and what it did to trust
sealtier jidoseal_changes '{"path":"~/notes"}'
sealtier jidoseal_changes '{"path":"~/notes","ref":"v1.2"}'

sealtier --version

Exit codes: 0 on success, 1 when a tool cannot complete (the error names the problem — a missing folder, a failed git status), 2 for usage errors.

MCP server

One bin serves both faces. The mcp subcommand starts a stdio MCP server:

npx -y @reneturcios/sealtier mcp

MCP client configuration:

{
  "mcpServers": {
    "sealtier": {
      "command": "npx",
      "args": ["-y", "@reneturcios/sealtier", "mcp"]
    }
  }
}

Tools

Frontmatter parsing is a small hand-rolled YAML subset (flat key: value pairs, quoted strings, inline lists/maps, one level of indented block maps and lists). A frontmatter block outside that subset is reported per file as frontmatter_ok: false; such a file reaches no tier and no field counts until it is fixed by hand.

Development

npm install
npm run build   # tsc -> dist/
npm test        # node test runner over test/*.test.ts, no network, fake git executor
npm run dev     # run the CLI from source via tsx
