MCP server directory

Routes an AI coding agent's code search through an official language-server index (clangd / Roslyn / tsserver / pyright) instead of grep, returning a token-capped `file:line` list with no source bodies — ~20× fewer tokens. Also symbol-level edit-by-name, a Bash-grep→indexed-query rewrite hook, and git/p4 output compaction. Local-only, no IDE. Claude Code plugin + `vts` CLI.

CI for [ink](https://github.com/inkle/ink) interactive-fiction stories. Compiles, exhaustively playtests every branch, and finds runtime errors (with a repro path), unreachable knots, and every distinct ending — so an agent can verify the story it wrote. Writes no prose. `claude mcp add inkcheck -- npx -y inkcheck mcp`

Operator leaderboard measuring users, not models — ranks AI coding operators by token cascade efficiency (Yield = Cache Reads × Output / Input²). 15 MCP tools: rank, pull, submit (ed25519-signed), diagnose, simulate. Privacy-first: only token counts leave the machine. `npx sigrank`

MCP server for Claude to talk to ChatGPT and use its web search capability.

C++26 paper reference MCP (`cpp26-ref`) backing a Claude Code plugin: `lookup_paper`, fuzzy `search`, `compiler_status` over a 216-paper ISO/IEC 14882:2026 corpus. The plugin's skill + reviewer subagent use these tools to bias Claude toward reflection, contracts, `std::execution` senders, `#embed`, expansion statements — even when the local compiler lags. 95% on a held 39-task eval gate.
