Why it matters

Most coding-agent developers today who want their agent to plug into a code editor (Zed / VS Code / JetBrains) have been either (a) writing custom JSON-RPC bridges per editor (no canonical protocol), (b) reaching for non-standard integrations like stdin / stdout file-watch that require custom agent-side code, or (c) maintaining separate transport layers per editor. agentclientprotocol/agent-client

Who should use it

Coding-agent developers building new agents that need editor integrations + code-editor developers wanting to embed a coding agent in their product without building a custom protocol bridge + AI agent developers standardizing on ACP for their agent / client integration + SDK / framework authors building downstream ACP clients or agents + anyone integrating coding-agent capabilities into a code editor (Zed / VS Code / JetBrains / etc.) + any developer wanting a clean Apache-2.0 open standard for editor <-> agent communicationEditor/agent developers + 5-SDK users that want the 5 first-party SDKs (Rust `agent-client-protocol` + `agent-client-protocol-schema` crates on crates.io; Kotlin `acp-kotlin` for JVM; Java `java-sdk`; Python `python-sdk`; TypeScript `@agentclientprotocol/sdk` on npm) -- the right 5-SDK primitive for any developer who has been writing custom transport-layer code per languageEditor/agent developers + JSON-Schema-v1-v2 users that want the JSON Schema artifacts at `schema/v1/schema.json` + `schema/v2/schema.json` attached to GitHub `schema-v*` releases -- the right JSON-Schema primitive for any SDK generator author who needs stable schema structure for code generationEditor/agent developers + protocolVersion-negotiation users that want the `protocolVersion` field in `initialize` for wire-compat negotiation -- the right protocolVersion primitive for any protocol author who has been fighting schema-vs-wire compat driftEditor/agent developers + agentclientprotocol-com-adoption-directories users that want the Agents + Clients + official Libraries + Community Libraries directories on `agentclientprotocol.com` -- the right adoption-directories primitive for any developer who has been searching for an editor/agent pair that supports a canonical protocolEditor/agent developers + JSON-RPC-envelope users that want the JSON-RPC envelope over stdio / WebSocket -- the right JSON-RPC-envelope primitive for any developer who has been writing custom request/response wrappers per transport

About this signal

ACP: Apache-2.0 Open Standard (Current Stable v1) for Connecting Any Code Editor to Any Coding Agent (JSON-RPC, 5 SDKs) is tracked by RepoRadar as a tool in the Radar section. It was first seen on 2026-07-08 and last updated on 2026-07-08. The current verdict is 'try now' with a Gold tier and moderate setup difficulty. Across RepoRadar's eight signals, ACP: Apache-2.0 Open Standard (Current Stable v1) for Connecting Any Code Editor to Any Coding Agent (JSON-RPC, 5 SDKs) is strongest on workflow potential (10.0) and practical usefulness (9.0) and weakest on setup ease (6.4) — a profile worth weighing against your own priorities. This page summarizes the evidence RepoRadar has captured from captured source metadata. The score, tier, risk label, and verdict on this page are never influenced by sponsorship, ads, or tips — they reflect only the usefulness, popularity, novelty, momentum, maturity, and evidence signals described in the RepoRadar methodology.

How this item is evaluated

RepoRadar assigned ACP: Apache-2.0 Open Standard (Current Stable v1) for Connecting Any Code Editor to Any Coding Agent (JSON-RPC, 5 SDKs) a composite score of 9.0 out of 10, placing it in the Gold tier. This score combines weighted sub-signals: usefulness (35%), novelty (18%), momentum (14%), maturity (10%), open-source/build quality (7%), evidence quality (6%), workflow potential (6%), and setup ease (4%). Popularity is tracked separately at 0.0 and never affects the composite score or tier. The risk label of 'low' reflects inherent user-impacting hazards, not generic novelty. Items with no risk flag may still require normal code review before production use.

Risk explanation

The 3; 600* / 296-fork / 16-subscriber repo is at active maintenance with the protocol v1 stable but the consumer SHOULD note the project is a protocol + SDK bundle (not a single binary); so adoption requires integrating one of the 5 SDKs (Rust / Kotlin / Java / Python / TypeScript) into an existing editor or agent -- not a drop-in install; the consumer SHOULD note the protocol is JSON-RPC over stdio / WebSocket.
