Codex MCP Servers

Choose by task and evidence

An MCP server connects an agent to tools or data through a declared transport. Choose the service and permission boundary before choosing an installation route. A hosted HTTP connection can have different authentication and cost requirements from a local stdio package. These listings keep registry facts separate from GitHub observations, and unknown fields remain visible. Read a source-based assessment, check the publisher setup for your client and begin with a small read-only task. A registry entry, repository star count or numeric score does not establish that a connection is safe, free or suitable for private data.

Agent labels reflect detected manifests or repository setup documentation. The runtime of each entry has not been tested in every client. Use the evidence links to check your exact client and version.
