GitGuardian MCP Server
OfficialEnables AI agents to scan projects for leaked secrets and manage security incidents using GitGuardia...
Open the FastMCP connection interface
- Click the "Install Now" button to open the FastMCP / MCP install dialog where you can enter environment variables. All ENV values described below should be added in that connection interface (the form fields provided by FastMCP).
Default (recommended) — use the built‑in OAuth flow (no ENV required)
- If you leave OAuth enabled (default), you do NOT need to pre-fill a token: after installation the MCP server will open a browser to authenticate you and will store the resulting token under ~/.gitguardian for future runs. (github.com)
If you want a Personal Access Token (PAT) instead of OAuth — obtain a PAT and paste it
- Log in to your GitGuardian Dashboard (your workspace).
- Open the "API" area → "Personal access tokens" (or "Personal access tokens" under API) and click Create token. (docs.gitguardian.com)
- Give the token a name, set an expiry (or never), select the scopes you need (e.g., scan, incidents:read, honeytokens:read/write depending on features you intend to use), then click Create.
- Copy the token immediately (it is shown only once) and paste it into the FastMCP interface field named GITGUARDIAN_PERSONAL_ACCESS_TOKEN. (docs.gitguardian.com)
- In the FastMCP env fields also set ENABLE_LOCAL_OAUTH to false (because you are supplying a PAT). (github.com)
If you need HTTP/SSE (remote) transport — set MCP_PORT / MCP_HOST and disable local OAuth
- In the FastMCP interface set ENABLE_LOCAL_OAUTH = false, MCP_PORT = <port you choose, e.g. 8000>, and MCP_HOST = <host, e.g. 127.0.0.1 or 0.0.0.0>. (github.com)
- When using HTTP/SSE, the server requires per-request authentication (Authorization header). You can either:
- Keep GITGUARDIAN_PERSONAL_ACCESS_TOKEN set in the FastMCP env (fallback), or
- Supply Authorization: Bearer
on each HTTP request to the MCP server. (github.com)
If you use a self‑hosted GitGuardian instance — set the instance URL
- Obtain the URL of your self-hosted GitGuardian instance from your admin (for example, https://dashboard.mycorp.local or the EU SaaS URL https://dashboard.eu1.gitguardian.com).
- Add that value into the FastMCP env field GITGUARDIAN_URL. (github.com)
If you have a custom OAuth application — set GITGUARDIAN_CLIENT_ID
- Only needed if your organization created a custom OAuth client for GitGuardian. Obtain the client ID from your GitGuardian admin or from the OAuth app registration area in your GitGuardian instance and paste it into GITGUARDIAN_CLIENT_ID in the FastMCP interface. If you don’t have a custom client, you can leave this unset (the MCP server defaults to the standard client). (github.com)
Optional scope and token options (fill if required)
- If you need extra OAuth scopes or want to control token lifetime, set GITGUARDIAN_SCOPES (comma-separated scopes) and/or GITGUARDIAN_TOKEN_LIFETIME (days) in the FastMCP env fields. Only set these if your deployment requires broader permissions or a non-default lifetime. (github.com)
Secure handling and final steps
- After pasting any token into the FastMCP interface, confirm the install. Store the token in a secrets manager if possible; PATs are shown once and cannot be recovered later — copy and keep them safely. (docs.gitguardian.com)
Quick checklist to paste into the FastMCP form
- For OAuth (default): no env required (install and authenticate via browser).
- For PAT-based or non-interactive usage: ENABLE_LOCAL_OAUTH = false, GITGUARDIAN_PERSONAL_ACCESS_TOKEN =
. - For HTTP/SSE transport: ENABLE_LOCAL_OAUTH = false, MCP_PORT =
, MCP_HOST = , (optionally) GITGUARDIAN_PERSONAL_ACCESS_TOKEN. - For self-hosted: GITGUARDIAN_URL =
. - For custom OAuth: GITGUARDIAN_CLIENT_ID =
. - Paste each value into its matching FastMCP ENV field and complete the Install/Save action in the interface. (github.com)
