@meridiantoolkit/mcp

@meridiantoolkit/mcp

MCP server for the Meridian business-services platform. Exposes services, service requests, workflow steps, payments and meetings as Model Context Protocol tools and resources. MCP is a protocol, not a host-specific plugin format — this server runs unchanged in Claude Code, Codex CLI, Claude Desktop, pi, or any other MCP-compatible client.

Install

cd meridian-mcp
npm install
npm run build

Or once published:

npx @meridiantoolkit/mcp

Configure

Copy .env.example or set env vars directly:

Var	Description	Default
MERIDIAN_API_URL	Meridian app base URL	http://localhost:3000
MERIDIAN_API_KEY	mrd_ API key (Better Auth) for REST calls	(none — tools return placeholder hint until set)
DATABASE_URL	Optional direct DB access fallback
MERIDIAN_MCP_LOG_LEVEL	debug/info/warn/error	info

More: /.well-known/agent-configuration exposes Agent Auth discovery (capability-based, short-lived JWTs, device-auth/CIBA approval). Agents can use either a long-lived mrd_ key or scoped Agent Auth grants — see meridian-skills meridian-api skill.

Without MERIDIAN_API_KEY every tool still responds — it explains what endpoint would be called and what to configure, so the server is safe to run in dry-run / demo mode.

Run

npm start            # stdio MCP server
npm run dev          # watch mode via tsx

Claude Code

claude mcp add meridian -- node /absolute/path/to/meridian-mcp/dist/index.js
# or, once published:
claude mcp add meridian -- npx -y @meridiantoolkit/mcp

Or drop a .mcp.json in your project root (shareable with a team, checked into git):

{
  "mcpServers": {
    "meridian": {
      "command": "npx",
      "args": ["-y", "@meridiantoolkit/mcp"],
      "env": {
        "MERIDIAN_API_URL": "http://localhost:3000",
        "MERIDIAN_API_KEY": "..."
      }
    }
  }
}

Codex CLI

Codex reads MCP servers from ~/.codex/config.toml (or a project-scoped .codex/config.toml for a trusted project):

[mcp_servers.meridian]
command = "npx"
args = ["-y", "@meridiantoolkit/mcp"]
env = { MERIDIAN_API_URL = "http://localhost:3000", MERIDIAN_API_KEY = "..." }

Or via the CLI: codex mcp add meridian -- npx -y @meridiantoolkit/mcp. The same config is shared by Codex CLI, the IDE extension, and the ChatGPT desktop app.

Codex has no plugin/skill system (unlike Claude Code and pi) — its equivalent of meridian-plugin/meridian-skills is just this MCP server plus project guidance. Copy AGENTS.md.example into your project's AGENTS.md for the same tool-usage guidance the skills packages give elsewhere.

Claude Desktop / pi

Add to your MCP config (Claude Desktop: claude_desktop_config.json; pi: .pi/settings.json → mcpServers, or pi --mcp):

{
  "mcpServers": {
    "meridian": {
      "command": "node",
      "args": ["/absolute/path/to/meridian-mcp/dist/index.js"],
      "env": {
        "MERIDIAN_API_URL": "http://localhost:3000",
        "MERIDIAN_API_KEY": "..."
      }
    }
  }
}

pi --mcp meridian-mcp/dist/index.js
# or via npx after publish
npx @meridiantoolkit/mcp

Tools

Tool	Description
meridian_status	Check API connectivity/config and list available tools/resources. No params. Works the same in every client — this replaces the pi-only meridian_status extension tool from meridian-plugin so status-checking isn't tied to one host.
list_services	List services (filter: categorySlug, isActive, countryCode)
get_service	Get service by id/slug with formConfig
list_categories	List service categories
list_service_requests	List requests (filter: status, customerId, providerId, limit)
get_service_request	Get request by id with steps
create_service_request	Create request (serviceId, answers, customTitle)
update_request_status	Patch request status (prefer advance_step)
get_workflow_status	Current phase + all requestSteps
advance_step	Complete current step → next step
list_request_steps	All RequestSteps in order
get_payment_status	Payment row for a request
verify_payment	Server-side verify with Flouci (Tunisia, local) or Stripe (international)
list_meetings	List meetings (filter: serviceRequestId, status)
create_meeting	Create Teams meeting + invites
respond_to_meeting	RSVP ACCEPTED/DECLINED/PENDING

Resources

URI	Description
meridian://services	Service catalog JSON
meridian://workflow	Workflow backbone + phases

Development

npm run typecheck
npm run build
npm test          # spawns the built server over stdio and exercises every tool/resource

Publish

npm login                     # once per machine
npm publish --access public   # required for the first publish of a scoped package
