"Canonical" matching MCP servers:

Open-source MCP server that exposes Signet cryptographic tools over stdio. It provides tools to generate Ed25519 keypairs, sign MCP actions, verify Signet receipts, and compute canonical content hashes for AI agent audit and accountability workflows.

Scans MCP servers for prompt-injection, tool-poisoning, and SSRF vulnerabilities using 30+ canonical rules across 5 severity tiers, with optional signed safety reports for procurement.

Enables governed access to a canonical Customer Graph across CRM and customer-service records, with per-field provenance, propose-only identity merges, field-level masking, records-only reply drafting, tiered policy and kill-switch enforcement, and hash-chained receipts for auditable reads and internal writes.

Enables LLMs to read a user-owned, local-first memory store kept in a portable folder (USB, SSD or laptop), with per-profile permissions limiting what each client can see and access cut off when the pocket is locked or unplugged. Also lets models propose new memories for the user to review and approve, keeping provenance and keeping canonical memory free of direct model writes.

MCP server for AI search crawler governance, brand safety, and search infrastructure auditing. Provides tools to audit robots.txt, canonical links, sitemaps, redirects, and send IndexNow notifications.

Enables local LLM agents to inspect Docker containers and optionally perform guarded restarts through MCP, with read-only defaults, credential redaction, canonical ID checks, denylists, and bounded daemon timeouts. It provides secure, zero-trust Docker daemon access for MCP clients.

Enables board members, secretaries, and management to conduct governance workflows through their own MCP agents, including maintaining canonical records, enforcing permissions and procedures, and confirming binding acts with tamper-evident audit evidence.

An MCP server that enables coding agents to safely verify npm/PyPI packages, retrieve cited briefs, discover GitHub repos, and fetch canonical docs, with fail-closed OSV vulnerability checks and injection-hardened output.

Cross-chain decentralized Web3 identity protocol. Canonical naming resolvable across all EVM networks via Chainlink CCIP and EIP-3668.
