Tools (25)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • bash

    Run a shell command in the workspace and return stdout, stderr, and exit code.

  • convert_time

    Convert time between timezones

  • covenant_agent_passportAgent identity and validation recordsread-only

    Partial identity facts for an MPL Core agent asset plus Covenant validation envelopes whose AppData write authority and payload fields pass record-authenticity checks. This endpoint does not fully decode the MIP-014 registry account or verify committed evidence. On-chain URIs are returned as untrusted data and are never fetched.

  • covenant_payment_historyObserved PayAI-sponsored transfer historyread-only

    Coverage-limited inbound USDC transfers found in recent transactions sponsored by the PayAI fee payer. Reports missing transactions explicitly. Fee sponsorship alone does not prove an x402 request, settlement receipt, completed job, or reputation.

  • covenant_verifyVerify attestation signatureread-only

    Verify the integrity of a covenant.attest.v1 envelope. A valid signature proves authorship by the carried signer, not that the signer is trusted. Supply expected_signer from an independent trust source when authorship matters.

  • edit_file

    Replace an exact, unique substring in an existing file. Fails if old_string is missing or appears more than once.

  • get_current_time

    Get current time in a specific timezones

  • mizuki_assess_repository

    Report whether a public GitHub repository qualifies for Mizuki maintenance and which command Mizuki would run to validate a change. Not a quote, and reserves nothing. Worth calling before quoting.

  • mizuki_bounties

    List public maintenance bounties created after eligible jobs receive a full refund.

  • mizuki_bounty

    Inspect one maintenance bounty, its claim requirements, separate AI review, maintainer approval, and funded SOL escrow status.

  • mizuki_capabilities

    Inspect proposed capability changes and the evidence required before a change can reach production.

  • mizuki_capability_handoff

    Read a hashed record of the failures, benchmark, and approvals required before a capability change can reach production.

  • mizuki_job_status

    Read delivery, pull request, validation, and refund state for a Mizuki maintenance job.

  • mizuki_payment_status

    Safely check whether an exact quote and idempotency key already reserved a job. This read never requests a wallet signature or submits payment. Requires a jobs:read MIZUKI_API_TOKEN.

  • mizuki_preflight

    Run repository, authorization, scope, and maintainer readiness checks for one issue without creating a quote or payment. Requires a repositories:read MIZUKI_API_TOKEN.

Show 10 more tools
  • mizuki_quote

    Get a fixed-price quote and x402 payment requirements for a public GitHub issue. With MIZUKI_API_TOKEN, the repository must already be connected and the quote is linked for payment recovery.

  • mizuki_repositories

    List repositories linked to the authenticated maintainer and their current readiness. Requires a repositories:read MIZUKI_API_TOKEN.

  • mizuki_repository_issues

    List bounded maintenance candidates for a linked repository after authenticated maintainer checks. Requires a repositories:read MIZUKI_API_TOKEN.

  • mizuki_repository_readiness

    Read current readiness for one repository already linked to the authenticated maintainer. Never bypasses maintainer or GitHub App checks.

  • mizuki_status

    Read delivery, PR, validation, or refund status for a Mizuki job.

  • mizuki_submit

    Submit a quoted job with a wallet-created x402 PAYMENT-SIGNATURE.

  • mizuki_treasury

    Inspect the refund reserve wallet status and planning estimates derived from service records. Planning estimates do not prove custody or grant spending authority.

  • name

    description

  • read_file

    Read a UTF-8 file from the workspace.

  • write_file

    Create or overwrite a UTF-8 file in the workspace.
