What to fix (3)

107 parameter(s) across 35 tool(s) have no description.

Add a "description" to each parameter with its format and an example ("ISO 8601 date, e.g. 2026-10-17"). This is the commonest cause of wrong arguments on the first call. How to fix →

Tools: principia.canonical_items.list, principia.canonical_items.lookup, principia.canonical_items.search, principia.canonical_priors.lookup, principia.canonical_priors.search and 30 more

35 tool name(s) contain "." or exceed 64 characters, which OpenAI-compatible function calling rejects (^[a-zA-Z0-9_-]{1,64}$).

Use "_" or "-" instead of "." and keep names to 64 characters, so clients built on OpenAI-style tool calling don't have to rename (or drop) them. How to fix →

Tools: principia.canonical_items.list, principia.canonical_items.lookup, principia.canonical_items.search, principia.canonical_priors.lookup, principia.canonical_priors.search and 30 more

In the last 30 days: 1 tool(s) removed and 0 schema change(s).

Add new tools or optional parameters instead of renaming or removing; deprecate first (say so in the description) and remove later. Agents cache tool contracts. How to fix →

Auto-fix: 35 corrected tool definitions

Paste-ready definitions with the problems above fixed. Changes marked verify need a human look. 35 tool(s) still need parameter descriptions written by someone who knows the API. All of them as JSON: /v1/readiness/mcp-registry%2Fcom.peopleprincipia%2Fprincipia/fixes

How do I install Peopleprincipia Principia MCP server?

Point your MCP client at this streamable-http endpoint: https://peopleprincipia.com/api/mcp

Is the Peopleprincipia Principia MCP server safe to connect to an AI agent?

Glimind scanned all 35 tool definitions for tool-poisoning patterns — hidden or invisible characters, instructions that override the model, concealment from the user, requests to read credential or MCP config files, conversation exfiltration and cross-tool shadowing — and found none. This checks what the server tells the model, not what its code does; review the source before granting access to sensitive data.
