smplkit MCP Server

A hosted, agent-native Model Context Protocol server — the gateway that lets an AI agent (Claude Code, Claude Desktop, Cursor, …) operate the whole smplkit platform on your behalf, without you ever leaving the chat.

One server, the whole platform:

• Flags — feature flags with per-environment values and targeting.
• Config — keyed, typed config with per-environment overrides.
• Logging — change runtime log levels per environment.
• Audit — search the audit log and wire SIEM forwarders.
• Jobs — scheduled HTTP jobs (cron, one-off, or on-demand) with response capture.

Once connected, tell your agent "turn on the new checkout for enterprise users in prod," "set the staging database host," "raise the SQL logger to DEBUG in prod," "stream audit events to Datadog," or "POST my endpoint every morning at 7." It makes the change, proves it works, and answers follow-up questions straight from the live state.

It is a thin, stateless HTTP client to the smplkit product APIs — it holds no credential of its own.

Connect once

1. Add the server and sign in

The server lives at https://mcp.smplkit.com/api/mcp. Point your MCP client at that URL — the first time it connects, the client opens your browser for a one-time sign-in (Continue with Google or Microsoft, standard OAuth). After that it reconnects and refreshes access on its own; there's no key to mint, copy, or rotate.

Claude Code (CLI):

claude mcp add --transport http smplkit https://mcp.smplkit.com/api/mcp

…or in .mcp.json:

{
  "mcpServers": {
    "smplkit": {
      "type": "http",
      "url": "https://mcp.smplkit.com/api/mcp"
    }
  }
}

Cursor (~/.cursor/mcp.json or project .cursor/mcp.json):

{
  "mcpServers": {
    "smplkit": {
      "url": "https://mcp.smplkit.com/api/mcp"
    }
  }
}

Claude Desktop (claude_desktop_config.json) — Desktop bridges remote servers through mcp-remote, which opens a browser for the one-time sign-in and caches the connection:

{
  "mcpServers": {
    "smplkit": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.smplkit.com/api/mcp"]
    }
  }
}

Prefer a static key?

For non-interactive use — CI, scripts, headless clients, or writing code with the smplkit SDKs — skip the browser and authenticate with an API key as a bearer token. Sign up at https://smplkit.com (Google or Microsoft SSO, email-verified instantly), create an API key in the console, and send it as Authorization: Bearer YOUR_SMPLKIT_API_KEY (a custom X-Smplkit-Api-Key header is also accepted). The SDKs read the same key from SMPLKIT_API_KEY. For example, add a headers block to the config above:

{
  "mcpServers": {
    "smplkit": {
      "type": "http",
      "url": "https://mcp.smplkit.com/api/mcp",
      "headers": { "Authorization": "Bearer ${SMPLKIT_API_KEY}" }
    }
  }
}

2. Ask your agent

"Create a boolean flag new-checkout, off by default, then turn it on in prod only for enterprise users."

"List my environments, then set database.host to db-staging.internal for staging."

"Raise the sqlalchemy.engine logger to DEBUG in production while I debug, then reset it."

"Test whether https://http-intake.logs.datadoghq.com/... accepts a sample, then create a Datadog forwarder for our audit events."

"POST https://api.example.com/cache/warm every morning at 7am NY time, then run it now to prove it works."

Tools

All tools share intent-named verbs — list_*, get_*, create_*, set_*, delete_* — and hide the JSON:API envelopes, per-environment nesting, and full-replace PUTs behind partial-intent calls.

Capability	Tools
Flags	create_flag, list_flags, get_flag, set_flag, delete_flag
Config	create_config, list_configs, get_config, set_config_value, delete_config
Logging	set_log_level, list_loggers, get_logger, reset_logger
Audit	query_events, get_event, list_forwarders, create_forwarder, test_forwarder, delete_forwarder
Jobs	create_job, list_jobs, get_job, update_job, delete_job, run_job, list_runs, get_run
Platform	list_environments

A few load-bearing behaviors:

• set_flag / set_config_value / set_log_level are read-modify-write. You express a partial change in one environment and the tool preserves the rest.
• list_environments tells you the valid environment targets (production, staging, …) for every set_* tool and for jobs.
• Prove before you trust. run_job fires a job once and returns the captured response; test_forwarder dry-runs a SIEM destination before you save it.
• create_job infers the kind: a cron schedule → recurring, a run_at datetime → one-off, neither → manual. You never set a kind.

The bundled SKILL.md teaches an agent the whole surface.

The public-internet constraint

smplkit calls job targets and forwarder destinations from the cloud, so those URLs must be reachable from the public internet — localhost/private addresses won't fire. To target a local server, point at its deployed URL or expose it with a tunnel (cloudflared tunnel --url http://localhost:PORT or ngrok http PORT) and set a secret auth header.

Development

python3.13 -m venv .venv && . .venv/bin/activate
pip install -r requirements-test.txt
pytest                                          # unit tests (acceptance deselected)
ruff check src tests

Run the server locally:

PYTHONPATH=src uvicorn smplkit_mcp.app:app --host 0.0.0.0 --port 8000
# MCP endpoint:  http://localhost:8000/api/mcp
# Health check:  http://localhost:8000/health

Configuration (env vars) — each product's base host is independently configurable, mirroring the SDK's base_domain pattern:

• JOBS_BASE_DOMAIN / FLAGS_BASE_DOMAIN / CONFIG_BASE_DOMAIN / LOGGING_BASE_DOMAIN / AUDIT_BASE_DOMAIN / APP_BASE_DOMAIN — the host for each product API (defaults <product>.smplkit.com; APP_* backs list_environments).
• *_SCHEME — https (default) or http.
• *_BASE_URL — full base-URL override (e.g. http://localhost:8002); wins over the two above. Used for the local platform and tests.

Acceptance tests

tests/test_acceptance.py provisions an ephemeral verified account and drives the full tool surface against the real product APIs end-to-end — create/set/get/ delete a flag, set and read a config value, set and list a log level, query events, create/test/delete a forwarder, list environments, and the eight Jobs tools — then cleans up. These tests require smplkit-internal admin credentials, so they self-skip unless an admin key is available (ADMIN_API_KEY env or the [admin] profile in ~/.smplkit) — external contributors can ignore them; the unit suite needs no credentials. Run them explicitly:

pytest -m acceptance
# point at a non-prod platform with <PRODUCT>_BASE_URL=...

Architecture

• Stateless Python service built on FastMCP: it holds no database and no platform credential of its own.
• Auth is per request — whether the caller signs in with OAuth or sends an API key, the credential is validated and used per request to reach each product API, and is never cached or logged.
• One thin JSON:API HTTP client per product (flags, config, logging, audit, environments), each pointed at its own configurable base host.
• The MCP endpoint is served under /api/mcp with a stateless, JSON-response transport (no long-lived SSE), so it behaves correctly through proxies and load balancers with short idle timeouts.
