GitHub MCP Server alternatives (2026)

GitHub MCP Server: Official MIT GitHub MCP. Use for GitHub; use Composio when you need 1000 apps.

Its Catch: Vs Composio (multi-app auth fabric): this is GitHub-only, official, and PAT/OAuth scoped to GitHub.

Below: 8 free or free-tier tools from the same category (MCP servers and tools), free and open source first, then the closest match by shared tags. Each keeps its own Catch.

  1. 1.mcp-agentApache-2.0 MCP-as-runtime + durable Temporal workflows (LastMile)

    Free / OSS · Apache-2.0 · 8.6k GitHub stars · quiet 180d+

    VerdictApache-2.0 MCP-native agent runtime. Compose MCP + Temporal; cloud is optional.

    CatchVs FastMCP (build MCP servers), Agno/VoltAgent/AG2 (general agent frameworks), and SuperGateway/mcp-remote (transport glue): mcp-agent is MCP-first agent runtime + durable workflows, not a coding CLI and not transport plumbing. LastMile cloud deploy/login is optional — day-one is OSS you run. Temporal ops are yours if you turn durability on.

  2. 2.SuperGatewayMIT stdio↔SSE/WS bridge for MCP transports

    Free / OSS · OSS/MIT · 2.9k GitHub stars

    VerdictMIT MCP transport bridge. Wire stdio to remote clients; expect zero new capabilities.

    CatchPlumbing only — not a Playwright/Chrome DevTools MCP capability server. It does not add browser, docs, or symbol tools; it only rewires transport. If your client already speaks the server’s native transport, you do not need it.

  3. 3.FastMCPApache-2.0 framework to build MCP servers/clients/apps

    Free / OSS · Apache-2.0 · 28.1k GitHub stars

    VerdictApache-2.0 MCP framework. Ship servers with it; do not confuse it with a tool marketplace.

    CatchBuild MCP apps ≠ use live MCP servers. Distinct from Playwright MCP / Context7 / Serena (capability servers) and from SuperGateway (transport glue). Horizon paid optional for ops at scale; day-one path is OSS FastMCP alone.

  4. 4.mcp-remoteMIT npx stdio↔remote MCP proxy with OAuth support

    Free / OSS · OSS/MIT · 1.6k GitHub stars

    VerdictMIT remote-MCP stdio shim. Use until your client speaks OAuth remote natively.

    CatchVs SuperGateway (bidirectional stdio↔SSE/WS bridge): mcp-remote is the client-side remote+OAuth drop-in, not a capability server and not a full gateway product. Some clients already speak unauth remote MCP — you only need this for OAuth/legacy stdio hosts. Adds a local Node process in the path.

  5. 5.MCP InspectorMIT official MCP server debugger — web, CLI, and TUI

    Free / OSS · OSS/MIT · 11.1k GitHub stars

    VerdictOfficial MIT MCP inspector. Test servers here; ship them elsewhere.

    CatchDebug surface, not a production MCP gateway or registry (see Smithery) and not transport glue (SuperGateway/mcp-remote). You still author servers elsewhere (FastMCP, etc.). v2 is the active line; pin versions in CI.

  6. 6.mcp2cliMIT runtime MCP/OpenAPI/GraphQL→CLI — zero codegen

    Free / OSS · OSS/MIT · 2.4k GitHub stars

    VerdictMIT MCP/OpenAPI/GraphQL CLI wrapper. Shell tools without shipping schemas every turn.

    CatchVs SuperGateway / mcp-remote (transport bridges) and MCP Inspector (debug UI): mcp2cli is a runtime CLI façade for APIs/MCP, not a gateway product and not an inspector. GraphQL mode needs introspection. You still trust whatever endpoint you point it at.

  7. 7.mcp-useMIT fullstack TypeScript MCP — servers, apps, clients, agents

    Free / OSS · OSS/MIT · 10.8k GitHub stars

    VerdictMIT fullstack MCP kit. Build servers and Apps; Manufact is optional soft upsell.

    CatchVs FastMCP (Python MCP framework), mcp-agent (MCP-as-runtime + Temporal), and Composio (managed tool/auth catalog): mcp-use is fullstack MCP app/server kit, not a multi-SaaS OAuth fabric. Manufact Free is an optional hosted/upsell path — core stays MIT you run yourself.

  8. 8.RowboatApache-2.0 local-first AI coworker — knowledge graph + MCP

    Free / OSS · Freemium · 18k GitHub stars

    VerdictApache-2.0 local AI coworker. Graph memory + MCP; paid cloud is optional.

    CatchVs OpenClaw / Continue / Claude Code (coding seats) and Mem0/Letta (memory runtimes): Rowboat is a full coworker desktop with graph memory, not a library you embed. Hosted Starter/Pro plans are paid convenience; OSS/local path is the free forever bar. Shell access on your machine means trust boundaries matter.
