Connect AI Agents to EVC Mesh

EVC Mesh MCP Server

Model Context Protocol (MCP) server for EVC Mesh - a task management platform for coordinating humans and AI agents.

Connects AI agents (Claude Code, Cursor, Cline, OpenClaw, etc.) to EVC Mesh via MCP tools for task management, persistent memory, event publishing, and multi-agent coordination.

Prerequisites

• Go 1.22+
• Running EVC Mesh instance
• Agent registered in Mesh with an API key (agk_...)

Installation

go install github.com/entire-vc/evc-mesh-mcp@latest

Or build from source:

git clone https://github.com/entire-vc/evc-mesh-mcp.git
cd evc-mesh-mcp
go build -o evc-mesh-mcp .

Tool Profiles

The MCP server supports two profiles to optimize context window usage:

Set via MESH_MCP_PROFILE environment variable. Default: full.

Configuration

Claude Code (stdio mode)

Add to your project's .mcp.json:

{
  "mcpServers": {
    "evc-mesh": {
      "command": "evc-mesh-mcp",
      "env": {
        "MESH_API_URL": "https://your-mesh-instance.example.com",
        "MESH_AGENT_KEY": "agk_your-workspace_your-key",
        "MESH_MCP_PROFILE": "core"
      }
    }
  }
}

Cursor

Add to Cursor MCP settings (Settings → MCP Servers):

{
  "evc-mesh": {
    "command": "evc-mesh-mcp",
    "env": {
      "MESH_API_URL": "https://your-mesh-instance.example.com",
      "MESH_AGENT_KEY": "agk_your-workspace_your-key",
      "MESH_MCP_PROFILE": "core"
    }
  }
}

SSE Mode (multi-agent, shared server)

For connecting multiple agents through a shared MCP endpoint:

MESH_API_URL=https://your-mesh-instance.example.com \
MESH_MCP_PORT=8081 \
evc-mesh-mcp --transport sse

SSE mode serves two profiles simultaneously on different paths:

Authentication per connection via:

• Authorization: Bearer agk_... header
• X-Agent-Key: agk_... header
• ?agent_key=agk_... query parameter

Agent Context Protocol (ACP)

At session start, follow these 5 steps in order:

1. heartbeat(status="online")              → register as alive
2. get_project_knowledge(project_id)       → load accumulated decisions & conventions
3. get_my_rules(project_id)                → understand constraints
4. get_context(project_id)                 → see recent activity + project knowledge
5. get_my_tasks()                          → check assigned work

At session end:

publish_event(type="summary", memory={persist: true})  → broadcast + persist
session_report(model, tokens_in, tokens_out)           → report metrics

Architecture

AI Agent (Claude Code / Cursor / Cline / OpenClaw)
    ↕ MCP (stdio or SSE)
EVC Mesh MCP Server (core or full profile)
    ↕ REST API (HTTP)
EVC Mesh API Server
    ↕
PostgreSQL / Redis / NATS / S3

The MCP server is a lightweight proxy - it translates MCP tool calls into REST API requests. No direct database access needed.

Deploy checklist (prod server - no CI)

evc-mesh-mcp has no CD pipeline; deploys are manual. Mandatory order (per
CLAUDE-workflow.md §1b Deploy Discipline):
migrate (goose up) → binary swap → restart. Never swap the binary before migrations pass.

# 1. Build for the prod target
GOOS=linux GOARCH=amd64 go build -o evc-mesh-mcp .

# 2. Copy binary to prod
scp evc-mesh-mcp root@prod-host:/opt/evc-mesh-mcp/evc-mesh-mcp.new

# 3. On the prod host: run migrations FIRST, then swap binary
ssh root@prod-host

  # STEP 1 - Run evc-mesh DB migrations (mcp server reads the same DB).
  # goose CLI is not installed on the host - use the official docker image.
  # If this exits non-zero, STOP - do NOT swap the binary.
  DB_URL=$(grep ^DATABASE_URL /opt/evc-mesh/.env.prod | cut -d= -f2-)
  docker run --rm --network host \
    -v /opt/evc-mesh/migrations:/migrations \
    ghcr.io/pressly/goose:latest \
    goose -dir /migrations postgres "$DB_URL" up

  # STEP 2 - Swap binary (only after migrations succeed)
  mv /opt/evc-mesh-mcp/evc-mesh-mcp /opt/evc-mesh-mcp/evc-mesh-mcp.bak.$(date +%Y%m%d-%H%M%S)
  mv /opt/evc-mesh-mcp/evc-mesh-mcp.new /opt/evc-mesh-mcp/evc-mesh-mcp

  # STEP 3 - Restart
  sudo systemctl restart evc-mesh-mcp

  # STEP 4 - Smoke test
  curl -sf http://localhost:8081/health || echo "SMOKE FAILED"

evc-mesh-mcp does not run its own migrations - it relies on the evc-mesh API's
schema. The goose step above ensures the schema matches before the new binary serves traffic.
