Claude Code Bridge From Essential AI Solutions (Essentialai.Uk)
Let separate Claude Code sessions exchange messages and coordinate work through a local MCP bridge.
Overview
Claude Code Bridge is a MCP server for the Build phase that bridges message passing between Claude Code CLI sessions using local stdio and configurable state.
What is this MCP server?
- stdio MCP server via npx @essentialai/cc-bridge-mcp-server
- Bridges inter-session communication between Claude Code CLI instances
- Configurable state path (CC_BRIDGE_STATE_PATH), timeouts, and log level
- Points CC_BRIDGE_CLAUDE_PATH at your claude executable
- Stale-session and message char-limit guards via environment variables
- Package version 0.3.0 per registry metadata
- Default CC_BRIDGE_TIMEOUT_MS 120000 ms
- Default CC_BRIDGE_STATE_PATH ~/cloud_code_bridge
What problem does it solve?
Running two or more Claude Code sessions leaves you manually copying context because nothing natively routes work between instances.
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: Builders who only use a single agent session or need cloud-hosted multi-user collaboration with RBAC.
What do I get? / Deliverables
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
Recommended MCP Servers
Journey fit
Multi-session agent coordination is core Build-phase agent tooling when one repo needs parallel specialist sessions. Agent-tooling is the canonical shelf for MCP servers that extend how Claude Code instances talk to each other, not app feature code.
How it compares
Local Claude Code session bridge, not multi-file edit atomicity or XRPL escrow payments.
Common Questions / 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.
