A docs site, SDKs in ten languages, an MCP server for agents, and monitoring that tells you when those SDKs break in production. One spec generates all four and keeps them current.

SDK Studio
Ten languages, zero forks
Idiomatic client libraries in 10 languages. Configure them, don't fork them. Auto-publish to every registry.

Monitoring
Errors traced to a commit
What breaks, and why. Errors grouped and traced to a commit, from your SDKs or your own backend.

MCP
Your API as agent tools
Your API becomes context and callable tools for Claude, Cursor, and any MCP client.

Docs worth reading, from the spec you already have #
AI writes the first draft for every endpoint. You edit it like a document. Nobody has to open the YAML.
- Three-column endpoint pages with schema trees that open a level at a time
- Live “try it” playground on every endpoint
- MDX guides alongside the generated reference
- Your own domain on every tier, Free included
Ten languages, built to your conventions #
Rename methods, exclude endpoints, pick your HTTP engine and folder structure. Then let it publish itself.
- Per-language config for namespaces, pagination, idempotency and code style
- Custom hooks you write, compiled into the client
- Auto-publish to npm, PyPI, Maven, crates.io, RubyGems and more
- Build history so you can see exactly what shipped and when
Find out what breaks before your customers tell you #
Two ways in: flip it on and the telemetry compiles into your generated SDKs, or drop the standalone package straight into your backend. Either way, there's no agent to deploy and nothing to instrument.
Logs
Query structured events directly by level, route, status code or release.
Issues
Errors grouped by fingerprint, each with the function and file that threw it.
Traces
One request end to end across client, server, cache, database and queue, with the slow span called out.
Service map
Every service, the calls between them, and the error rate on each edge.
N+1 queries
The same query fired in a loop, found for you and counted across traces.
Uptime
Synthetic probes on a schedule, with the run history behind every endpoint.
Alerts
Fire on burn rate and regressions, so a single stray 500 never wakes anyone.
Security
Credentials and identifiers are redacted client side before an event leaves your process, then again at ingest.
Monitoring is off by default and switches on from the dashboard. Credentials and direct identifiers, from tokens to email, phone and IP, are redacted on the client side, before an event leaves your process, then again at ingest. Personal context waits on your app's consent, under a pre-signed GDPR Article 28 DPA.
Stop agents from hallucinating your API #
MCP is how an agent reaches something it was never trained on. Without it, Claude or Cursor integrates your API from memory. With it, one command turns your project into a server they connect to. Then they list your real endpoints and call them.
- Seven documentation tools to search, read and navigate your docs
- One callable tool per endpoint , so the agent can hit your API for real
- Curated by SDK Studio , so your exclusion list becomes the agent's permission list
- One line to install :
npx @octri/mcp, with nothing to host
Is your spec ready for code generation? #
Paste your OpenAPI URL and get a score out of 10, on the same rules the SDK Studio runs. You see every missing schema, undeclared path parameter and awkward method name, before anyone generates a client from it.
An example audit runs alongside: a readiness score of 6.8 out of 10 across 24 operations, with the rules the spec passed and failed scrolling past it.
What the fourteen rules check, and what each one costs a generated SDK.
Change one. All four follow #
Deprecate an endpoint in API Studio and the SDKs mark the method, the agent tools stop offering it, and monitoring shows you who still calls it. Add a language, cut a release, push a new spec: the same thing happens. There is one source underneath all four, so there is never a second place to go and update.
Everyone else stops at “here's your SDK.” #
That's the moment your code leaves your visibility. It runs on someone else's machine, fails on someone else's machine, and you hear about it in a support ticket three days later.

From spec to shipped in an afternoon #
The whole pipeline from one OpenAPI spec: API documentation, client libraries in ten languages, an MCP server and production monitoring.
Connect your spec
Upload a file or link a GitHub repo. Coming from Postman or AsyncAPI? We translate it.
Review the draft
AI writes docs for every endpoint. Edit anything, publish when it reads right.
Pick your languages
Configure the SDKs, flip on monitoring, build. They publish themselves.
Push to repository
Every spec change reruns the whole pipeline. Docs, SDKs, agent tools, all in sync.
One spec, ten client libraries #
Every client is generated from the same OpenAPI document and published to the registry its own users already install from.
Already on something else? #
We read your existing config and bring it across: navigation, custom pages, SDK settings and all. You don't start from a blank project. Want a hand with the move? A call with us and our onboarding help are both free of charge.

Notes from building it #
What we learn shipping specs, SDKs and telemetry, written up properly.
Questions #
Plans, spec changes, editing the generated docs and SDKs, training data and self-hosting.
No. Plans are not per-product, so you can leave one switched off and turn it on months later without redoing anything you have already set up.
