Pricing: https://agentreadychecklist.com/pricing.md (free). # AR-ACT-10: An MCP server or a CLI AR-ACT-10 is a MUST on the act layer: A product agents are expected to act on exposes at least one interface an agent can act through: an MCP server (AR-ACT-03) or a CLI (AR-ACT-06). It applies to products agents act on (not informational sites). 19 of 19 platforms have a recipe below. 3 cited facts back it. ## The requirement Identifier AR-ACT-10 Level MUST Layer Act Applies to products agents act on (not informational sites) Checked by Ora, matched on this site, Verify Kit mcp-or-cli Ora check [mcp-server, cli-tool](#ora) The statement A product agents are expected to act on exposes at least one interface an agent can act through: an MCP server (AR-ACT-03) or a CLI (AR-ACT-06). ## Why - AR-ACT-10 is new in v2.0 and adds a MUST, so a product that conformed to v1.0 may not conform to v2.0.primary source, 2026-10-20: [github.com/agentready-org/standard/blob/main/CHANGELOG.md](https://github.com/agentready-org/standard/blob/main/CHANGELOG.md), read 2026-11-04 - The spec says a purely informational site conforms on AR-FIND and AR-READ alone.primary source: [github.com/agentready-org/standard/blob/main/spec/spec.md](https://github.com/agentready-org/standard/blob/main/spec/spec.md), read 2026-11-04 - The spec says not to ship an empty surface to meet the requirement.primary source: [github.com/agentready-org/standard/blob/main/spec/spec.md](https://github.com/agentready-org/standard/blob/main/spec/spec.md), read 2026-11-04 ## How to verify ### [MCP server or CLI discoverable](https://agentreadychecklist.com/kit/mcp-or-cli/) ```bash curl -fsSL https://agentreadychecklist.com/kit/verify.sh | bash -s -- https://example.com --only=mcp-or-cli ``` Fetches /.well-known/mcp/server-card.json and /.well-known/mcp.json, POSTs an MCP initialize to /mcp, and, if the reader names a CLI package, checks the npm registry for it. PASS on any one. **It cannot prove:** Cannot judge whether the tools are useful or whether OAuth completes; a POST to /mcp is the one non-GET call and is skipped with --get-only. ### The one-line version Run the kit mcp-or-cli check: /.well-known/mcp/server-card.json or /mcp answers, or the CLI named in the docs resolves on npm. ## Verify with Ora 2 checks in Ora's catalogue (contract 1.38.0, read 2026-11-05) read this row. Each entry says what the check looks at and why this page lists it. - `mcp-server` MCP server / manifest Looks for a Model Context Protocol server or manifest. Usability, 6 points, required; catalogue applicability all. Listed because: same name, `mcp server`. - `cli-tool` CLI tool available Looks for an official command line tool. Usability, 3 points, recommended; catalogue applicability domain-only. Listed because: same name, `cli`. ### Run just these checks ```bash curl -s -X POST https://ora.ai/api/scan/checks -H 'content-type: application/json' -d '{"url":"https://example.com","checkIds":["mcp-server","cli-tool"]}' ``` This calls the endpoint Ora documents for re-verifying a fix. It sends no cache, returns a result for each id and no total score, and spends one scan from the daily budget. Replace the URL with yours. [How to re-verify one fix](https://agentreadychecklist.com/guides/re-verify-one-fix-with-ora/). ### Or audit the whole site ```bash npx ax@0.10 audit https://example.com --min-score 70 ``` Exit code 1 means the score is below the number you passed, so the same line gates a deploy: [the CI recipe](https://agentreadychecklist.com/guides/gate-deploys-on-agent-readiness-in-ci/).
