CAUTION· not started

Publisher claims: "CLI-first semantic code search with MCP integration and interactive D3.js visualization for exploring code relationships" Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Not started: dependency install failed; the server itself was not observed.
Tested
the dependency install step · every file read, file written and host contacted by what ran
Not tested
server startup · the tool list · tool behavior

What this means for the label: Caution here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Before you give it your token

It will ask for
AWS_ACCESS_KEY_IDAWS_SECRET_ACCESS_KEYGITHUB_TOKENHOMEBREW_TAP_TOKENOPENAI_API_KEYOPENROUTER_API_KEYConfiguration, not credentials: ANTHROPIC_BEDROCK_BASE_URL, BEDROCK_MODEL, HOMEBREW_TAP_REPO, INDEX_PATH, MCP_CODE_ENRICHMENT, MCP_ENABLE_FILE_WATCHING, MCP_PROJECT_ROOT, MCP_VECTOR_SEARCH_HYBRID_CHUNK_EMBEDDING, PROJECT_ROOT
Where it talks to
no vendor host named in the codeAlso astral.sh, endpoint.com, openrouter.ai — not the publisher's domain; check what for before connecting.
What the honeypot saw
no credential files read · no network
What we could not test
server startup · the tool list · tool behavior

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names astral.sh, endpoint.com, openrouter.ai as well as its own vendor. The guard injects AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, GITHUB_TOKEN, HOMEBREW_TAP_TOKEN, OPENAI_API_KEY, OPENROUTER_API_KEY only into requests to the host you bind (and its subdomains) and refuses the rest.

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-10 and scored it 73/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Pipe-to-shell pattern; Pipe-to-shell pattern. Summary: no network, touches nothing outside the project, writes no memory.
