One key to every
tool your AI touches.
Lumen is the universal connection layer for AI agents. One endpoint hands Claude, Cursor, Codex — any agent — every tool, model and API it will ever need. No keys to manage. No SDKs. Pay only for what it uses.
Paste into Claude → Connectors. Live in under a minute.
Connects every agent to everything they run on
ShopifyShopifyEvery new tool used to cost you a week.
Agents are only as capable as the things they can reach. Wiring up each one by hand is where the magic quietly dies. Lumen deletes that work.
Wiring it up yourself
- A new MCP server to host for every single tool
- OAuth flows, API keys and tokens scattered everywhere
- Secrets baked into prompts the model can read
- Nineteen invoices, zero idea what your agent actually spent
- No spend caps — one runaway loop drains the account
- Rebuild and redeploy every time you add a capability
With Lumen
- One MCP endpoint. Paste it once, into any agent
- Credentials held, scoped and rotated in an isolated vault
- The model never sees a secret — ever
- One pre-funded wallet, metered to the cent, live
- Hard caps per agent, per tool, per day
- Add a provider and it's callable instantly — no redeploy
From zero to omni-capable in under a minute.
Connect once
Paste a single MCP endpoint into Claude, Cursor, Codex or any agent. No SDKs, no per-tool OAuth dance, no credential vault to babysit.
lumen connect --agent claudeFund your wallet
Top up once. Lumen meters every call to the cent and pays each provider on your behalf. One invoice instead of nineteen.
lumen wallet fund $50Call anything
Your agent discovers and calls every tool, model and API the moment it's online. Permissions, rate limits and spend caps enforced at the edge.
agent → lumen → 4,200+ toolsWatch your agent reach across your whole stack.
Every call routed, authenticated, timed and metered through one endpoint — with a signed ledger you can actually trust.
Every tool your agent needs. Already connected.
Browse a slice of the 4,200+ providers reachable through Lumen. Search, filter, and your agent can call any of them the moment it's online.
Everything between your agent and the world.
One endpoint, every capability
Tools, LLMs, vector stores and raw HTTP APIs all sit behind a single MCP connection. Add a provider and it's instantly discoverable and callable — no redeploy, no new config. The whole stack, one surface.
Zero key management
Credentials are held, scoped and rotated in an isolated vault. Your agent never sees a secret.
Per-request metering
Pay for the exact calls your agent makes. Sub-cent precision, live in the dashboard.
Spend caps & guardrails
Hard ceilings per agent, per tool, per day. Approvals on the calls that matter.
Full call ledger
Every request, argument and response — signed, searchable, replayable. Audit-grade by default.
If it speaks MCP or HTTP, it speaks Lumen.
Drop one endpoint into the client you already use. No SDK to learn, no wrapper to maintain. The same connection powers your editor, your CLI and your production agents alike.
- Works in Claude, Cursor, Codex, Gemini CLI & custom agents
- Bring your own keys or use Lumen-managed credentials
- Switch models without touching a line of code

The honest answers.
A self-hosted MCP server is one tool, one process, one set of keys you maintain forever. Lumen is the whole catalog behind one managed endpoint — provisioned, authenticated, rate-limited and metered. You connect once and never touch infrastructure again.
Anything that speaks MCP or can call an HTTP endpoint: Claude, Claude Code, Codex, Cursor, Gemini CLI, Windsurf, Devin, Cline and your own custom agents. One config line each.
You pre-fund a wallet. Lumen meters every downstream call at cost plus a thin platform fee, pays each provider for you, and shows the running total live. No subscriptions, no minimums, no surprise invoices.
That's the point of the control plane. Set spend caps, scope tools per agent, require human approval on sensitive actions, and review a signed ledger of every call. Credentials live in an isolated vault the model never reads.
Yes. Use Lumen-managed credentials for the long tail, or bring your own for the providers you already pay for. Both route through the same endpoint and the same ledger.
Give your agent superpowers in one line.
Connect once. Fund a wallet. Watch your agent reach across every tool, model and API you run on — metered, guarded and yours.
