codegraph-mcp
This MCP server enables managing Git repositories via shallow clones and analyzing them with CodeGraph. It provides tools for adding, listing, updating, deleting repositories, and exploring codegraph status and exploration.
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.
repo_addAdd a repository with an HTTPS shallow clone. If id is omitted, derive it from the Git URL owner/name. Run codegraph init after adding it.
repo_listList all cloned owner/name repositories and their CodeGraph status.
repo_updateUpdate a shallow clone to the latest remote commit, then sync or initialize its CodeGraph index.
repo_deleteDelete a repository and its CodeGraph index.
codegraph_statusReturn the CodeGraph index status. Run codegraph init automatically when the repository is not indexed.
codegraph_exploreAnalyze the structure of a repository with CodeGraph. Run codegraph init automatically when the repository is not indexed.

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 — repo_add (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); repo_list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); repo_update (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.
Destructive tools are labelled
1 tool perform destructive updates without destructiveHint — repo_delete deletes at line 250 (fs.rm(repo.directory, { recursive: true, force: true }))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Tool inputs are validated
5/6 tool handlers declare input schemas (83%)
Declare an inputSchema with zod/joi/yup on every tool definition.
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.
Shell command execution
2 child_process/subprocess calls in production code — runs shell commands (src/index.ts:134, src/index.ts:147)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
