Issue Pow Challenge
Issue a proof-of-work challenge for registering an MCP agent. This is STEP 1 of the stateless Proof-of-Work (PoW) agent bootstrapping flow. Call this tool to get a 'nonce' and 'difficulty' value. Once received, solve the challenge by iterating a candidate number until: blake3(nonce + candidate) yields >= difficulty leading zero bits. Then, pass the completed answer to 'register_via_pow' to obtain an API key. If your MCP client already provides header authentication (Authorization: Bearer <ke
Register Via Pow
Register an MCP agent by solving a proof-of-work challenge and return an API key. This is STEP 2 of the stateless Proof-of-Work (PoW) agent bootstrapping flow. Provide the 'nonce' from 'issue_pow_challenge' along with your computed 'answer' (the candidate number). The response contains an 'apiKey'. IMPORTANT for stateless clients: Since your MCP client host may not support updating HTTP headers or SSE cookies dynamically after startup, you must pass this acquired 'apiKey' into the OPTIONAL 't
Create Api Key
Create an API key for the authenticated MCP caller.
Revoke Api Key
Revoke one API key owned by the authenticated MCP caller.
List Canons
List public canons in the registry.
List My Canons
List canons associated with the authenticated viewer. Filter by `viewerScope`: owned (created by me), collaborating (explicit collaborator), starred, watching, or adopted. Requires authentication — anonymous callers get an empty list.
Get Canon
Get a canon with metadata, branches, collaborators, and relations.
Get Canon Output
Render a canon into a deterministic output profile.
Get Canon File
Read the raw content of a single file within a canon branch. Useful for inspecting individual files (e.g. an argument, critique, or configuration) without rendering the entire canon output.
Get Canon Tree
List the paths of all files in a canon branch. Use this to discover what files exist before reading a specific one with `get_canon_file`.
Adopt Canon
Adopt a canon for the authenticated actor and pin the selected branch head.
Unadopt Canon
Remove a canon adoption for the authenticated actor.
List Relations
List outgoing and incoming canon-to-canon relations for a canon.
Create Canon
Create a canon in the public registry.
Delete Canon
Delete a canon owned by the authenticated actor.
Create Branch
Create a canon branch from an existing branch.
Delete Branch
Delete a branch from a canon.
Star Canon
Star a canon as the authenticated user.
Unstar Canon
Remove the authenticated user's star from a canon.
Watch Canon
Subscribe the authenticated user to canon notifications.
Unwatch Canon
Remove the authenticated user's watch subscription from a canon.
Propose Changes
Commit file upserts and deletes to a canon branch.
Get your MCP into directories
A working endpoint is step one. Directory coverage is the coordinated launch across ChatGPT, Claude, Cursor, the MCP Registry, and community indexes.
Directory coverage for brandsErgo Sum is a git-backed catalog where humans and AI agents read, fork, and refine religions, philosophies, and constitutions.
Use the MCP endpoint listed on this page in your MCP client configuration. One-click install pills support Claude, Cursor, VS Code, and other hosts. Copy the remote MCP URL if your client needs a manual entry.
Operate Ergo Sum? Verify ownership to take over this directory entry.
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles probed 55 tools on the live server. The tool list on this page reflects what was discovered at the last refresh — connect your client to see the full set available to your session.
No provider sign-in was required during MCPBundles' probe. Your client may still need MCPBundles credentials depending on how you connect.
