SnapKitty MCP Server (SNAPKITTYWEST/snapkitty-mcp) is an MCP server listed on the M8ven Trust Index. It scores 60 out of 100, grade C. It declares 6 tools. No publisher has claimed this listing.
MCP server exposing tools for WORM chain sealing, sovereign agent creation, Ada governance contract generation, and SSM state injection from Lean theorems.
Caution. Specific findings reduced this grade. They are listed on the page. 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.
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.
worm_sealSeal any payload into the SnapKitty WORM chain with SHA-256. Every event is chained to the previous seal — tamper-evident, append-only.
worm_readRead and optionally verify the SnapKitty WORM chain. Returns recent events and chain validity.
agent_buildCreate a sovereign agent manifest with class, capabilities, model binding, and WORM seal. Classes: SENTINEL, ORACLE, BUILDER, ARCHIVIST, BERSERKER.
ada_contract_generateGenerate an Ada-syntax sovereign governance contract for an agent. Defines permitted capabilities, trust level, and WORM-seals the contract.
twin_chatChat with a local Ollama model as a sovereign digital twin. Response is WORM-sealed. Requires Ollama running locally.
sovereign_injectGenerate a Mamba SSM injection specification from a Lean 4 theorem and Ada contract. This is the BOB orchestrator architecture: structured symbolic proofs injected into SSM state, bypassing the context window.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
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
6/6 tools missing one or more hints — worm_seal (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); worm_read (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); agent_build (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +3 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.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
