Ccs tools (5)
write = sends, deletes, buys or postsRead from the package source without running it. The installed server may list more.
audit_mcp_configAudit an MCP client/server configuration JSON for security risks: plain HTTP, weak secrets, disabled TLS, missing commands. Returns structured issues with severity.
issue_evidenceIssue a CCS evidence record for a tool call. Evidence is cryptographically bound (content_hash + evidence_hash), tamper-evident, independently verifiable. Issued for allowed AND denied calls.
verify_intent_bindingVerify that actual tool call arguments match a declared intent with zero tolerance. Catches cross-model parameter drift (planner says amount=100, executor writes amount=10000). No LLM needed — pure deterministic comparison. Supports exact match, numeric tolerance, and regex pattern binding modes.
verify_receiptOffline-verify a CCS Ed25519-signed receipt. Auditors call this with a receipt JSON produced by issue_evidence or verify_intent_binding; it checks the signature against the embedded signer_public_key and reports whether the body was tampered with. Optionally pin an expected signer public key (PEM string or sha256: fingerprint) to reject receipts from untrusted signers.
verify_tool_callVerify an AI agent tool call against CCS 7 dimensions (Structure, Schema, Security, Identity, Integrity, Latency, Cost) plus semantic attack-chain analysis and math overflow detection. Returns verdict (allowed/denied) with detailed findings. DEFAULT MODE BLOCKS UNSAFE CALLS.
