gray-matter

Item: gray-matter
Rating: 74
Author: M8ven

MCP gateway for the Gray Matter suite. Register ONE connector and get Neuron (semantic memory) + NeuRAG (knowledge base) as warm managed workers — combined pulse, context cache, cross-store bridges and a web control center.

Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.

// key findings

✅

No credential exfiltration, no sensitive file access, no obfuscation

Static analysis found nothing flowing your secrets to unexpected places.

✅

Open source with a license and README

Anyone can audit the code, the license is declared, and the publisher documents what it does.

🔐

You'll be asked for 3 credentials: GM_TURSO_AUTH_TOKEN, TURSO_AUTH_TOKEN, NEURAG_TURSO_AUTH_TOKEN

These are read from process.env at runtime. Make sure you trust where they’ll be sent.

// tools this server exposes8 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

gray_matter_pulse

Pre-context + knowledge chunks + flash. Calls neuron_get_context and neurag_query in parallel, merges the results, uses the cache.

gray_matter_status

Show Gray-Matter status: registered servers, cache, counters.

gray_matter_bridge

Persist a cross-store bridge: a link between a Neuron concept and a NeuRAG knowledge node the orchestrator found to relate. Recalled in future pulses on either endpoint.

gray_matter_state_set

Blackboard (GM, thalamus): publish key=value with an optional TTL in seconds. Keys are 'org/component/name'. Returns the entry with its version.

gray_matter_state_get

Blackboard: read key. None if missing or expired — state decays on its own.

gray_matter_state_delta

Blackboard: changes from version `since` onwards, filtered by key prefix (expired entries included).

gray_matter_brainstorm

Brain (GM, thalamus): pairs a seed with the most DISTANT items (lowest similarity) from Neuron (nodes) and NeuRAG (chunks) — unexpected candidates, ordered by distance. Requires 'seed'.

// environment variables

To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

8/8 tools missing one or more hints — gray_matter_pulse (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gray_matter_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gray_matter_bridge (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool test coverage

Only 0/8 tools referenced in tests (0%)

Write tests that reference each tool by name so every tool has at least one test.

Claim the listing to review these findings one by one and send us a correction where you disagree, straight to the team. Claiming also means we tell you when the grade moves, and reach you first if we find anything urgent.

// full audit trail

The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.

// improvement guidance — verified publishers only

We have 3 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
