AGNTCY

AGNTCY is the open collective for agent interoperability, initiated by Outshift — Cisco's incubation group — and governed under the Linux Foundation (LF Projects, LLC), developed in the open across 52 public repositories. It publishes specifications rather than a product API: OASF (Open Agentic Schema Framework) for describing agents with a versioned record schema and skill/domain taxonomies, the Agent Directory (DIR) for announcing and discovering multi-agent systems over gRPC, SLIM (Secure Low-Latency Interactive Messaging) as a transport, the Agent Connect Protocol (ACP) as a REST interface for invoking remote agents, and an Identity layer that issues and verifies W3C Verifiable Credential badges for agents, MCP servers and tools. One AGNTCY-operated API exists — the OASF Schema Server at schema.oasf.outshift.com, unauthenticated and callable by anyone; everything else is a specification you implement or software you deploy yourself. It ships SDKs in Python, JavaScript, Go, Rust and .NET, a local-stdio MCP server for the Agent Directory, and SLIMRPC transports for the A2A SDKs in five languages. Everything is Apache-2.0; there is no pricing, no paid tier and no commercial plan.

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles AGNTCY the way a machine reads it — 21 machine-readable artifacts across 5 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — AGNTCY scores 48.0/100 (developing), with a separate agent-readiness read of 46/100 (agent native). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

AGNTCY Kin Score — API readiness rating by API Evangelist

Put this on your own site. The badge is drawn live from AGNTCY's current Kin Score — paste it once and it updates itself every time the score is recomputed. It follows your visitor's light or dark setting, and it links back here so anyone who sees it can read the full breakdown.

How we profile AGNTCY

Each block below is one kind of artifact we hold for AGNTCY. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 5

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

OASF Schema API

The Open Agentic Schema Framework schema server API. Browse and retrieve the OASF schema, walk the skill / domain / module taxonomies, generate samples, translate taxonomy value...

Agent Connect Protocol (ACP)

A standard REST interface for invoking and configuring remote agents: agent discovery and descriptors, stateful threads, thread runs, and stateless runs, each with create / wait...

AGNTCY Identity Service API

Manages identity and access control in the AGNTCY ecosystem: register agents, MCP servers and tools as apps (including directly from an OASF record), issue and verify W3C Verifi...

AGNTCY Identity Node API

The identity node that generates and resolves agent IDs, registers issuers and serves their JWKS, and publishes, revokes, searches and verifies Verifiable Credentials. OpenAPI 3...

Agent Directory (DIR)

Distributed announce and discovery of multi-agent systems. gRPC-first, with services for storage (content-addressed by CID), routing over a DHT, structured search, signing and v...

MCP Servers 2

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

Event Specifications 1

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

JSON Schema 7

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Security Posture 3

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.

Where this information came from

This is an independent, third-party profile of AGNTCY, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
