MCP Reasoner with multiple reasoning strategies including Beam Search and Monte Carlo Tree Search
Mcp reasoner mcp server lets Claude, Cursor and other MCP clients work with MCP Reasoner directly. MCP Reasoner with multiple reasoning strategies including Beam Search and Monte Carlo Tree Search.
What happened to mcts-001-alpha and mcts-001alt-alpha? > Quite simply: It was useless and near similar to the base mcts method. After initial testing the results yielded in basic thought processes was near similar showing that simply adding policy simulation may not have an effect.
Once connected, the assistant can call these 2 tools directly:
MATH500 — GPQA-DiamondGMSK8 — Maybe Polyglot &/or SWE-BenchThe server is distributed via npm as npm, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. MCP Reasoner sits in that group, and the shape of its toolset — MATH500, GMSK8 — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
| Tool | What it does |
|---|---|
| MATH500 | GPQA-Diamond |
| GMSK8 | Maybe Polyglot &/or SWE-Bench |
