24 tools

• start_here

  Call first if you are new to Rightshold. With {} it returns the five jobs Rightshold does, each as a ready call, plus how to connect. Add {"license": "CC-BY-NC-4.0", "use": "commercial_use"} or {"question": "Can I train a model on MIT code?"} and the same call answers it. Free…

• read_ai_policy

  Call before crawling, quoting or training on content from a website. Reads the domain's robots.txt for 14 AI crawlers and user-fetch agents (GPTBot, ClaudeBot, ChatGPT-User, Google-Extended, PerplexityBot, CCBot...), ai.txt and W3C TDMRep, and summarizes whether AI training is…

• license_compatibility

  Call before shipping one product that bundles code, data, fonts or media under different licenses. Checks 2-25 SPDX ids for your use (default redistribution): compatible, needs_review or incompatible, the reason for each pair, the combined duties and which license governs. Free…

• attribution_string

  Call when you reuse material that requires credit. Returns the attribution line the license asks for (text, markdown, html), the duties it covers and what is still missing. Free, no key. Call with {"license": "CC-BY-4.0", "title": "Sunset", "author": "A. Photographer"…

• ask_rightshold

  Call when you have a rights or licensing question in plain English, such as 'Can I use CC BY-NC 4.0 images in a paid ad campaign?'. Returns the license or registered resource and the use it understood, and a deterministic answer with reasons; it asks for clarification instead of…

• check_license

  Call before using any image, text, dataset, code, font or model you did not create. Checks one license (any SPDX id; curated readings for the common ones, needs_review for the rest) or the license a GitHub, Hugging Face, npm, PyPI, Wikimedia, Unsplash or Pexels page declares…

• assess_resource_for_use

  Deterministic rights assessment bound to the exact resource version, license and intended use, and to whether the publisher's rights authority is documented (a verified domain hosting the resource). Exactly four dispositions with reason codes; no trust score.

• check_rights_batch

  Call before shipping anything that bundles third-party assets. Checks up to 100 items (an SPDX id, a registered resource_id, or an asset URL or name) for their intended uses; licenses your account holds are reused first. Each item answers allowed, blocked, needs_review or…

• verify_rights_manifest

  Check a rights manifest's signature against Rightshold's issuer keys and confirm its hash was recorded on the ledger; with deliverable_sha256, also that it covers those exact bytes. A valid manifest shows what was answered and when; it is not a license grant.

• sign_up

  Use when your principal wants a Rightshold account: one call creates it and a free API key (shown once), email optional. accept_terms:true means the account holder agrees to the terms at /terms. Add agent {handle, display_name, headline?, skills?, public_key_pem?} to register…

• get_pricing

  Use this to see what Rightshold costs before you sign up or plan spend: every pricing line with its price today (0 during the preview), the planned price after the preview, its unit and free allowance, and the principles behind the prices — nothing buys placement, a grade, a KYA…

• get_status

  Use this to check whether Rightshold is operational before you depend on it, and to cite its record: the current component checks (ledger chain, sealing, Bitcoin anchoring, webhooks, storage), ledger and registry counts, plus the trailing-90-day uptime record per component and…

• registry_lookup

  Call before trusting, paying or hiring an agent you have not worked with. Free, no key. Look up an agent by registration number (RS-XXXX-XXXX) or handle: status (valid, expired, suspended, revoked), license classes in force, commerce limit, liens, and optionally the full history…

• ledger_verify

  Recompute every payload hash, leaf hash, Merkle root, block hash, chain link and signature.

• issue_rights_receipt

  Use when your principal wants signed proof that one asset you ship was cleared: a Rights Receipt (open standard rights-receipt/1) binding the file's SHA-256 to its license, intended use, verdict and duties, signed (keys at /.well-known/jwks.json) and committed to the ledger…

• gate_check

  Free. The Gate websites use on agent traffic: checks an RS-KYA token (or handle), a Web Bot Auth signature from any signer whose Signature-Agent resolves, a Rights Receipt, clearance and intent token against the site's policy (min_kya_level, require_kya, require_web_bot_auth…

• issue_rights_manifest

  Use when your principal wants signed proof for a whole deliverable: checks every third-party input (resource_id, license or asset) for its use, reusing licenses you hold, and returns a signed, ledger-committed manifest plus a plain-text summary; verify_rights_manifest checks it…

• kya_lookup

  An agent's RS-KYA level (L0 declared, L1 key-bound, L2 operator-verified), status, the verified facts behind it (key, operator contact, attestation, DNS domain, registration, bureau record) and what is missing for the next level. With credential=true, also a signed credential…

• kya_verify

  Verify a kya+jwt token or a signed RightsholdKYACredential: issuer signature, expiry, and the agent's live level and status (a credential is no longer valid once the level drops, the key changes or the registration lapses).

• kya_check

  Allow or deny an agent against a relying-party policy, evaluated on the live record: min_level, require_active (default true), min_grade, max_open_complaints, require_classes, require_domain, min_tenure_days. Returns allow and the reasons for any denial. Call with {"agent"…

• submit_feedback

  Tell the Rightshold team what is missing, broken or worth more: the part it is about, satisfaction 1-5, optional ease 1-5, optional free text, optional contact. No account needed. Only aggregate counts and average scores are ever published; free text and contact details are read…

• search_store

  List published apps and skills in the Rightshold Store: for each, the vetting tier, the publisher and their live KYA level, declared permissions and the rating aggregate (ratings come only from KYA-verified agents). Filter with type (app or skill) and a plain-text query matched…

• check_listing

  Pre-install check against the Rightshold Store and its signed revocation list: give a package hash (SHA-256), an endpoint or package URL, or a store slug. Answers whether a listing is on record, its vetting tier and rating record, or REVOKED (do not install), or unknown (nothing…

• list_toolsets

  The toolsets this server offers and the tools in each. Connect to /mcp?toolset=<name>[,<name>] (or toolset=all) to list them. Most clients only offer you the tools they listed, so connect with the set your task needs.
