Greptile MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Greptile and the rest of your systems. It gives your agent 21 Greptile actions (19 reads and 2 writes) and holds the Greptile credential itself, so the agent never does. It paces Greptile's limits and records every call. Connecting Greptile needs your own Greptile OAuth app and one admin sign-in.

Set up

Connect Greptile in three steps.

  1. 01

    Add actionlake to Claude.

    Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

    https://connect.actionlake.com/mcp
  2. 02

    Connect Greptile.

    OAuth 2.0, authorization code with PKCE. You register your own OAuth app with Greptile, an admin signs in once, and you paste the app's client id and secret and the tokens from that sign-in; actionlake renews the access token from then on. actionlake stores what you paste write-only, sealed under your tenant's key.

    Before the first sign-in, Greptile needs an OAuth app of your own, registered in its developer portal. actionlake has no Greptile app to lend you.

    • access_tokenAccess token from one sign-in with your own OAuth app
    • refresh_tokenRefresh token from the same sign-in; the access token is renewed from it
    • client_idOAuth client id from Greptile's dynamic client registration (POST https://auth.greptile.com/oauth2/register with…

    Make the first call. Check before a write.

    Ask in plain words; Claude picks the action. Before anything changes, check validates the call and prices it, for free.

Top actions

The Greptile API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 5 of Greptile's 5 action names are shared with at least one other connector, so an agent learns them once.

Try it

Prompts to paste into Claude.

Each one names the Greptile actions it will call, so you know what it reads and what it changes before you send it.

Governance for Greptile

Every write can wait for a yes.

None of Greptile's actions is destructive. A key can still be held to reads, capped, and set so a person confirms every write.

A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

a key for this connector
account {  op: "keys.create", name: "greptile-agent",  allowed_actions: ["greptile.*"], cap_calls: 2000,  confirm_policy: "human_for_writes"}
Illustrative. Scoped to Greptile only, capped at 2,000 upstream calls, every write confirmed.

Cost

What Greptile costs on actionlake.

Every Greptile action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call Greptile refused with 401, 403, 429 or a 5xx are free. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Questions

The Greptile MCP server, answered.

Is there a Greptile MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 21 Greptile actions across custom contexts, code reviews, knowledge base documents and knowledge bases, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Greptile.

What do I need to connect Greptile?

Your own Greptile OAuth app, registered with Greptile (its client id and client secret), and the access and refresh tokens from one admin sign-in. actionlake has no Greptile app of its own, so this is not a one-step consent. actionlake renews the access token as it expires. The free call account { op: "connections.requirements", service: "greptile" } lists exactly what to paste.

Can an AI agent change things in Greptile?

Only if its key allows it. 2 Greptile actions write, and none is destructive. A key can be limited to reads, capped, and set so a person confirms every write.

Will an AI agent use up my Greptile API limit?

actionlake paces every call to the limits in the Greptile service file: 60 calls a minute per connection. Repeated reads are answered from cache (19 Greptile actions can be), which never reaches Greptile.

What does a Greptile action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (21 Greptile actions page). Cache hits, searches, dry runs and calls Greptile refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which Greptile API does it cover?

The Greptile (AI code review: pull requests, code reviews, review comments, custom context, knowledge base, analytics) API Greptile MCP Server 1.0.0 (https://api.greptile.com/mcp, MCP 2025-03-26) at api.greptile.com. It is built from Greptile's documentation as read on 23 October 2026. 21 actions in 13 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my Greptile data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Greptile credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
