Claude Code Bridge From Essential AI Solutions (Essentialai.Uk)
- eaisdevelopment/cc-bridge-mcp-server
Claude Code Bridge is a MCP server that bridges message passing between Claude Code CLI sessions using local stdio and configurable state.
About
Claude Code Bridge from Essential AI Solutions is a stdio Model Context Protocol server that connects multiple Claude Code sessions so they can coordinate instead of working in isolation. developers often spin up parallel sessions—for example, one for backend and one for tests—but lose context across windows; this bridge persists bridge state on disk and invokes the Claude CLI with tunable timeouts and logging. Install through npm as @essentialai/cc-bridge-mcp-server and register it in your MCP config alongside your primary Claude Code setup. Environment variables control where state and logs live, how long subprocess calls may run, optional message size limits, and log verbosity. It is intermediate complexity because you must understand multiple concurrent sessions and path configuration on your machine. The canonical journey placement is Build → agent-tooling: it does not ship your product by itself, but it upgrades how agents collaborate while you integrate features. It is a local developer bridge, not a hosted business suite or payment oracle.

What it does
Let separate Claude Code sessions exchange messages and coordinate work through a local MCP bridge.
Who is it for?
Power users running multiple Claude Code terminals on one machine who want structured handoffs without a custom orchestration script.
Skip if: Skip if you only use a single agent session or need cloud-hosted multi-user collaboration with RBAC.
What you get
After registration, your agent can use the bridge tools so separate sessions share state and CLI-driven messages under your timeout and path settings.
- MCP tools for cross-session Claude Code communication
- Persisted bridge state and logs under your configured path
- Tunable timeouts and optional message size limits for subprocess calls

FAQ
Who is Claude Code Bridge for?
It is for developers who run several Claude Code CLI sessions and want MCP-mediated communication between those instances on the same workstation.
When should I use Claude Code Bridge?
Use it during Build agent-tooling when parallel sessions should exchange work—for example frontend and backend agents—without manually pasting transcripts.
How do I add Claude Code Bridge to my agent?
Add an MCP stdio server entry that runs npx @essentialai/cc-bridge-mcp-server, set CC_BRIDGE_STATE_PATH and CC_BRIDGE_CLAUDE_PATH as needed, then reload MCP in Claude Code.
