--- title: "Harness Platform MCP server for AI agents - actionlake" description: "Give Claude 2,994 Harness Platform actions through one MCP server: ansible, pullreq. Your agent never holds the credential. 100,000 calls a month free." canonical: https://actionlake.com/connectors/harness-platform updated: 2026-10-23 --- Connectors · Developer & infrastructure # Harness Platform MCP server for AI agents. actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Harness Platform and the rest of your systems. It gives your agent 2,994 Harness Platform actions (1,545 reads, 1,092 writes and 357 that wait for a confirmation) and holds the Harness Platform credential itself, so the agent never does. It paces Harness Platform's limits and records every call. [Connect Harness Platform free](https://actionlake.com/console?start=sandbox) [See pricing](https://actionlake.com/pricing) 100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you. `claude mcp add --transport http actionlake https://connect.actionlake.com/mcp` the first call ``` do { action: "harness.account_roles.list_roles_acc", intent: "check which Harness Platform account is connected" } # List Roles · read · 1 upstream call ``` - 2,994 actions in one signed file - 1,545 read look, never change - 1,092 write create and update - 357 wait for a yes destructive, confirmed first Set up ## Connect Harness Platform 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 Harness Platform. API key. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key. - `api_key` Harness API key token: in Harness open your profile (or Account Settings > Access Control > Service Accounts),… - `account_id` Your Harness Platform account id - `host` Where your Harness Platform lives: your host ``` account { op: "connections.requirements", service: "harness" } # free: exactly what to paste, and what is found for you ``` 3. 03 ### 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. ``` do { action: "harness.account_roles.list_roles_acc" } # list roles · read · 1 upstream call check { action: "harness.account_roles.create_role_acc", input: { … } } # free: inputs, permissions, cost and confirmations, nothing sent ``` Harness Platform at a glance **Sign-in** API key.

Questions ## The Harness Platform MCP server, answered. **Is there a Harness Platform MCP server for Claude?** Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 2,994 Harness Platform actions across ansible, pullreq, repository and workspaces, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Harness Platform. **What do I need to connect Harness Platform?** Harness API key token: in Harness open your profile (or Account Settings > Access Control > Service Accounts),…. Plus your account id and your host. The free call account { op: "connections.requirements", service: "harness" } lists exactly what to paste. **Can an AI agent delete or change things in Harness Platform?** Only if its key allows it, and only with an explicit confirmation. 357 Harness Platform actions are destructive, including delete a Role, soft delete repository and delete a project. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it. **Will an AI agent use up my Harness Platform API limit?** actionlake paces every call to the limits in the Harness Platform service file: 300 calls a minute per connection. Repeated reads are answered from cache (1,288 Harness Platform actions can be), which never reaches Harness Platform. **What does a Harness Platform action cost?** One upstream call, the only unit actionlake bills. A list that pages bills one call per page (2,994 Harness Platform actions page). Cache hits, searches, dry runs and calls Harness Platform 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 Harness Platform API does it cover?** The Harness Platform: CI/CD pipelines, GitOps, Code, Artifact Registry, Feature Flags, Chaos, Cloud Cost, IaCM, STO, SRM and platform administration API Harness APIs (OpenAPI 3.0.3, spec 1.0) at app.harness.io by default, or the base URL set when you connect. It is built from Harness Platform's documentation as read on 23 October 2026. 2,994 actions in 485 areas, each one in the signed service file (version 1.0.0). **Does actionlake keep my Harness Platform 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 Harness Platform 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. ## More connectors like Harness Platform Shares the most action names with - [LaunchDarkly 27](https://actionlake.com/connectors/launchdarkly) - [Harbor 14](https://actionlake.com/connectors/harbor) - [Optimizely Feature Experimentation 13](https://actionlake.com/connectors/optimizely-feature-experimentation) - [Bitrise 13](https://actionlake.com/connectors/bitrise) - [Sourcegraph 13](https://actionlake.com/connectors/sourcegraph) - [Spacelift 9](https://actionlake.com/connectors/spacelift) Joins with, on shared entities - [HaloPSA 2](https://actionlake.com/connectors/halopsa) - [Unified.to 2](https://actionlake.com/connectors/unified-to) - [ERPNext (Frappe) 2](https://actionlake.com/connectors/erpnext-frappe) - [Jibble 2](https://actionlake.com/connectors/jibble) - [Workato 2](https://actionlake.com/connectors/workato) - [SonarQube Cloud 2](https://actionlake.com/connectors/sonarqube-cloud) Browse - [All Developer & infrastructure connectors](https://actionlake.com/connectors/category/developer-and-infrastructure) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
