Protocol3.5/4 points
Coverage: hygiene only (0 of 11 tools reached with a valid call). Only protocol hygiene was graded, so the A says little about what the tools do.
Protocol checks
| Check | Verdict | What happened |
|---|---|---|
| protocol Valid MCP handshake and tool schemas | pass | handshake ok, 11 well-formed tool(s) |
| tool-poisoningcritical No tool-poisoning indicators in tool metadata | pass | scanned 11 tool definition(s), including parameter text: nothing suspicious |
| robust-input Survives malformed tool input | partial | 0 internals leak(s), 16 invalid call(s) accepted |
| secret-echocritical No environment secret echoed in responses | pass | canary secrets absent from tools/list and 40 captured response(s) |
What was not covered
- Database: Not applicable. Server config has no {dsn}/{host}/... Placeholder, so the harness cannot start the server once per role
- HTTP: Not applicable. The server is started over stdio; the http pack needs server.url
- Files: Not applicable. No tool is classified as taking a file path with medium confidence or higher
- Git: Not applicable. No tool is classified as taking a git repository path with medium confidence or higher
- Network: Not applicable. No tool is classified as taking a URL with medium confidence or higher
- SQLite: Not applicable. No tool takes a SQL string
- Effects: Not applicable. No tool takes a harness-owned target (file path, repository or URL) with medium confidence or higher
- Tools that a server lists only for clients that declare roots, sampling or elicitation capabilities are not seen: the harness declares none
- Tool "create_entities" is covered by the core checks only: the tool has no string parameters; its required parameter "entities" cannot be filled by the harness; write a probes: entry to call it
- Tool "create_relations" is covered by the core checks only: the tool has no string parameters; its required parameter "relations" cannot be filled by the harness; write a probes: entry to call it
- Tool "add_observations" is covered by the core checks only: the tool has no string parameters; its required parameter "observations" cannot be filled by the harness; write a probes: entry to call it
- Tool "delete_entities" is covered by the core checks only: string parameters only, and none names a path, URL, command, SQL or repository; add it under tools: to include it
- Tool "delete_observations" is covered by the core checks only: the tool has no string parameters; its required parameter "deletions" cannot be filled by the harness; write a probes: entry to call it
- Tool "delete_relations" is covered by the core checks only: the tool has no string parameters; its required parameter "relations" cannot be filled by the harness; write a probes: entry to call it
- Tool "read_graph" is covered by the core checks only: the tool takes no parameters; add it under tools: to include it
Run it yourself
Started with the standard settings like this; put it in sealmark.yaml as the server:
npx -y @itseasy21/mcp-knowledge-graph@1.0.7
Each of 613 verdicts was checked independently, and Sealmark was wrong on some: how reliable Sealmark is.
