Split MCP Server (Harness FME)

Updated June 2026

The Split MCP Server (Harness FME) MCP server, built by kud (Community), provides split.io was acquired by Harness and rebranded to Harness FME (Feature Management & Experimentation) — a `splitio/mcp-server` repo does not exist, and Harness has not published a first-party MCP server for it. It is community-built and best for Coding & Dev.

About

Split.io was acquired by Harness and rebranded to Harness FME (Feature Management & Experimentation) — a `splitio/mcp-server` repo does not exist, and Harness has not published a first-party MCP server for it. The best available option is kud/mcp-harness-fme, a community-built, MIT-licensed TypeScript server exposing 30 tools across workspaces, environments, feature flags, flag definitions, segments, rule-based segments, and change requests. It supports a zero-config startup that reads the `MCP_HARNESS_FME_API_KEY` environment variable and exits immediately if it is missing, plus a "kill & restore" flow that instantly forces all traffic to a flag's default treatment (or restores it) with a single tool call. Every destructive operation — delete, kill, archive, disable — requires an explicit `confirm: true` argument, preventing accidental changes from an agent acting on ambiguous instructions. It also supports the full change-request flow for rule-based segments, letting teams submit segment-definition changes with optional approvers for orgs that require approval gates. Install with `npx --yes @kud/mcp-harness-fme@latest`, or add it directly via `claude mcp add --transport stdio --scope user harness-fme --env MCP_HARNESS_FME_API_KEY=your_api_key -- npx --yes @kud/mcp-harness-fme@latest` in Claude Code. An optional `get_flag_url` deep-link tool activates when `MCP_HARNESS_FME_ACCOUNT_ID` and `MCP_HARNESS_FME_ORG_GUID` are also set. Works with any stdio MCP client — Claude Desktop, Claude Code, Cursor, Windsurf, Cline, Zed.

GitHub MCP Server

The GitHub MCP server is GitHub's official Model Context Protocol integration, giving AI assistants like Claude and Cursor direct, authenticated access to the GitHub platform and its full developer surface. With this MCP server, you can ask your AI to read and write repository files, create and merge branches, open and review pull requests, comment on and close issues, trigger GitHub Actions workflows, search across code repositories with GitHub's code search, and inspect commit history — all through natural-language prompts in your AI interface. Developers use it to supercharge code review workflows, automate issue triage, generate PR descriptions from diffs, bulk-update repository settings, and wire AI agents into CI/CD pipelines. The GitHub MCP server connects via a GITHUB_PERSONAL_ACCESS_TOKEN environment variable with scopes for the operations you need, keeping authentication clean and auditable. Install with Docker: `docker run -e GITHUB_PERSONAL_ACCESS_TOKEN=<token> ghcr.io/github/github-mcp-server` — or configure it as a remote MCP server in Claude Desktop, Cursor, VS Code, Windsurf, and Cline. With over 8,000 GitHub stars, it is the most widely deployed official code-platform MCP server and the reference implementation for AI-native GitHub automation.
