Is your product there? ### The directories are filling up Node8's August 2026 census counted 1,253 Claude connectors and 2,305 ChatGPT listings. Only 392 of 3,150 products were on both.

Claude now shows plugin publishers installs, listing views and the searches that lead to them. You can finally measure whether you are chosen.

Agent Distribution Engineering is the work of making an existing SaaS product listed, working and chosen inside AI agents: tool design, auth, evals, directory submission and measurement after launch. We don't build agents. We make your product usable by the agents your customers already use. - **Not generic MCP development:** a server is one deliverable; we're accountable for the listing, the review and whether agents pick your tools. - **Not a replacement for AI coding tools:** they write code; we own tool design, review rules, evals and submission. - **Not an OpenAPI-to-MCP generator:** generators mirror endpoints; we design 8 to 20 tools around real jobs. [What Agent Distribution Engineering covers](https://invokary.com/agent-distribution-engineering) ## Listed, working and chosen, then growing. We measure each one. 1. ### Listed A live public listing on every surface you contract, published from your organization. Measured by listing URLs and tier (Community or Verified). 2. ### Working Every tool succeeds on valid input and auth works first time. Measured by eval pass rate of 90% or more, tool error rate under 2%, uptime of 99.5% or more. 3. ### Chosen The agent picks the right tool, and people find your listing. Measured by tool-selection accuracy of 85% or more, plus listing views and search queries where the platform reports them. 4. ### Growing Adoption rises month over month. Measured by installs by surface and version, weekly tool calls and connected accounts over 90 days. ## From your OpenAPI spec to a reviewed connector. We do not generate one tool per endpoint. We map your API to 8 to 20 tools shaped around real jobs, because models get unreliable with large tool lists. Every tool ships with a title, the right read-only and destructive hints, and a description written for the model, not at it. 1. API We start from the API you already have, and from your OpenAPI spec if there is one. 2. Tool design 8 to 20 tools shaped around real jobs, each with a title, read-only and destructive hints, and a description written for the model. 3. MCP server A remote MCP server on the 2026-07-28 spec, in your repo and on your domain. 4. OAuth OAuth 2.1 with Client ID Metadata Documents, plus a Dynamic Client Registration fallback. 5. Evals Five positive and three negative prompts per platform, run in CI. 6. Submission A submission package for each platform, submitted from your accounts. 7. Discovery Listings in the directories you choose, with names and descriptions that help agents pick your tools. 8. Usage Installs by surface and version, weekly tool calls and connected accounts after launch. Built on the current MCP spec (2026-07-28), with OAuth 2.1 and Client ID Metadata Documents, evals in CI and code in your repo. ## Why not have Claude Code or Cursor write it? You can, and for an internal tool you should. A listed connector is a different job: each platform reviews it against its own rules, real customers sign in through OAuth, and a model has to pick your tools from everything in its context. An AI coding assistant can write a working server. The rest is what we sell: choosing 8 to 20 job-shaped tools, auth that passes review, evals that show the right tool gets picked, submission from your accounts, and fixes when reviewers or the spec change. For example, [OpenAI's reviewers need test accounts that work without MFA](https://invokary.com/platforms/chatgpt#chatgpt.reviewer-credentials), and [projects with EU data residency can't submit plugins](https://invokary.com/platforms/chatgpt#chatgpt.eu-residency). *How the options compare* | | In-house with AI coding tools | OpenAPI-to-MCP generator | Freelance MCP developer | Invokary | | --- | --- | --- | --- | --- | | Best when | Internal tools, or you have MCP and review experience in-house | You want a quick server from an existing spec | You have a defined spec and will run review yourself | You want a reviewed, listed connector at a fixed price | | Tool design | You decide | Mirrors your endpoints by default | Depends on the developer | 8 to 20 job-shaped tools with annotations, approved by you | | Auth that passes review | You design and test it | Varies by product | Depends on the contract | OAuth 2.1 with Client ID Metadata Documents, DCR fallback | | Evals | You build them | Varies by product | Depends on the contract | In CI: 5 positive and 3 negative prompts per platform | | Submission and review responses | Your team | Your team | Depends on the contract | From your accounts; 2 rejection cycles included | | After launch | Your team | Your team | Depends on the contract | 30 days of monitoring, then Care or a handover | | Price certainty | Engineering time | Tool pricing | Hourly or fixed | Fixed price, published acceptance criteria | ### Not a hosting platform. Not a generic agency. - Your code, your domain, your listing. We never host your production server. - Fixed prices and published acceptance criteria. - Built for the current spec, with a written plan for the next deprecation. - We submit from your accounts, so the listing is yours forever. ## What we can show you today. We are a new studio, so we will not show you logos we have not earned. Here is what we can show today: the requirements each platform's reviewers check, with sources and check dates, a dated log of platform changes, and our own open-source MCP server, listed in Claude's Connectors Directory, ChatGPT's Plugins Directory and the official MCP Registry. ### Mohd. Ashhar, founder. Full stack AI engineer who founded two AI products, Clauseium and ApplyForge, and builds LLM features for Ascendo AI, a client. [Who you work with](https://invokary.com/about) ### Founding client program. Our first five Launch Sprints are $7,500 instead of $9,500, in exchange for a public case study with your approval. ### Reference implementation (not a client) Our own MCP server: six read-only tools with full annotations, checked in CI against the ChatGPT submission's test cases, and listed in Claude's Connectors Directory, ChatGPT's Plugins Directory and the official MCP Registry.

No. Anthropic, OpenAI and Cursor decide. We build to their published requirements, fix what reviewers flag, and include two rejection cycles. ### Who owns the code? You do, on payment. It lives in your repository from the first commit. ### Do you host the server? No. It runs on your infrastructure or your Cloudflare, Vercel or AWS account. ### What do you need from us? An engineering contact for about 2 hours a week, OAuth admin access, a reviewer test account with realistic data, DNS access and a Claude Pro, Max, Team or Enterprise plan (on Team and Enterprise, an Owner submits). ### We already have an MCP server. We audit it, migrate it to 2026-07-28 and fix what blocks listing. That is the Upgrade. ### How is this different from an OpenAPI to MCP generator? Generators mirror endpoints. Reviewers and models reward a small set of well-described tools with correct annotations and real auth. [See how the options compare.](https://invokary.com#why-not-ai) ### Where are you based? We are an engineering studio based in India, working with SaaS teams in the US, UK and EU. We work 09:00 to 18:00 IST, which covers UK and EU mornings.
