"Coder" matching MCP servers:

Enables a primary coding agent to delegate bounded implementation and repair tasks to a local OpenAI-compatible model that edits a copy of the project, runs configured checks, and returns artifacts for review. Exposes stdio tools for capability discovery, task submission, progress polling, artifact reading, and cancellation.

Enables Codex to delegate long-running work to Claude Code via blocking MCP calls, with tools for model discovery, run, and resume without polling.

Routes AI tasks to appropriate local LLM models (quick, coder, MoE, thinking) with automatic model selection, multi-backend support (Ollama, llama.cpp, Gemini), and parallel processing capabilities.

A lightweight Model Context Protocol (MCP) orchestrator designed for efficiency at scale. It features TOON compression (reducing token usage by 30-90%) and Lazy Loading, making it the ideal solution for complex, multi-tool agentic workflows.

Lets one Codex instance send a task to another Codex instance on a different computer, enabling symmetric host-to-host collaboration including projectless tasks and local environment dependent work.

Enables bounded planner-to-coder-to-reviewer workflows with real file tools and a host-enforced verification gate, using Ollama by default. It supports CLI, TUI, and MCP stdio, plus bidirectional Rose/Neovim editor integration.

Signed, offline-verifiable authorization for API-contract changes. Before a contract change (OpenAPI, GraphQL, Protobuf, AsyncAPI, MCP manifests) merges or deploys, the agent calls preflight_change_set; the decision is deterministic, signed, and verifiable without calling CodeRifts. Three tools: preflight_change_set, verify_receipt, get_decision_details. Only a granted change can proceed.

Enables bidirectional, asynchronous task delegation between Codex and Claude Code, plus optional DeepSeek API consultations, with workspace locking, recursion protection, and bounded permissions.

Enables external AI supervisors to oversee and steer native Codex through MCP, including thread and turn management, observation, interruption, approval responses, runtime status, and checkpointing.

Enables Codex to delegate tasks to interactive Claude Code sessions as role-controlled subagents for exploration, code review, and implementation, using the existing Claude Code installation on macOS.

Enables Codex to operate your already-open Firefox tabs via local MCP tools for status, tab management, navigation, interaction, and screenshots on Windows x64 with Firefox 140+.

The GEO check every vibe coder runs before they launch. MCP server that lints, auto-fixes, and tracks how AI agents discover any product. 6 tools — geo_check, geo_fix, geo_track_init, geo_prompts, geo_status, geo_corpus_query.

A local, repository-scoped MCP coordination bridge that lets Claude Code and Codex work together in the same checkout via tasks, leases, and evidence-based completion, preventing conflicting edits and enabling bounded delegation.

Enables Claude Code, Cursor, and Codex users to orchestrate plan/build/review workflows across host or CLI models with a spec gate, tool vetting, hard per-run and per-day cost/token limits, safe defaults, and clear logs.

Enables Claude Code to launch and supervise a background Codex collaborator through four MCP tools, while providing a local viewer for tracking task status and message exchanges.

Enables two-way collaboration between Claude Code and the Codex CLI: Claude can hand off plans for execution or adversarial review, while the working agent can block to ask Claude questions, report progress or findings, and receive mid-run corrections. Supports multiple named, resumable sessions per project with configurable model, effort, and sandbox settings.

A local stdio MCP server that lets any MCP client start a Codex thread and continue it by opaque thread ID through the codex and codex-reply tools, with fail-closed sandboxing and approval policies. It restores the removed Codex CLI MCP integration by bridging clients like OpenCode to the official Codex SDK.

A transparent message ferry between Claude Desktop and Claude Code CLI, enabling task delegation with any MCP configuration without the bridge needing to know about specific MCPs.

Enables selecting exact conversation excerpts, carrying forward only confirmed background and provenance, and handing the packaged selection to another agent for continuation.

Enables ChatGPT to supervise and control local Codex runtime sessions through a secure MCP interface, managing threads, turns, approvals, events, and recovery without exposing direct file, shell, Git, SSH, or model loop access.
