The MCP catalog shows what a connected MCP server exposes to Pioneer. Use the catalog before allowing agents to use a server.Documentation Index

Catalog items
An MCP server can expose:| Item | Meaning |
|---|---|
| Tools | Actions an agent can call |
| Resources | Readable external data |
| Resource templates | Parameterized resources |
| Prompts | Reusable prompt templates |
What to inspect
For each server, review:- display name
- transport type
- runtime status
- health diagnostics
- enabled/disabled state
- implicit/not implicit state
- tool count
- resource count
- prompts
- policy state
- recent audit activity
Enable, Disable, Or Change Implicit Mode
Disable MCP servers or tools until you understand what they expose. After they are trusted, decide whether they should be implicit. An implicit MCP tool can be picked up automatically when Pioneer decides it is relevant. A not implicit MCP tool stays available, but agents should use it only when you explicitly ask for that MCP capability. Use implicit mode for trusted read-heavy tools that are useful across many threads. Keep write-capable, sensitive, expensive, noisy, or production-facing MCP tools not implicit.Tool review checklist
Before enabling an MCP server in real workflows, ask:- What can each tool read?
- What can each tool write?
- Does it call external services?
- Does it need secrets?
- Does it modify production systems?
- Does it have rate limits?
- Does it return sensitive data?
- Should it be implicit, or only used when explicitly requested?
Server lifecycle
From the desktop app you can manage server lifecycle actions such as:- start
- stop
- restart
- update policy
- uninstall
- inspect details
Troubleshooting
Server is auth required
Server is auth required
Add or refresh the required secret or token, then restart the server.

Some catalog items may have failed. Review diagnostics and restart after fixing dependencies.
Tools do not appear in a thread
Tools do not appear in a thread
Confirm the MCP server is installed for the same gateway and that policy allows it in the current workspace.

Check server logs, gateway connectivity, credentials, input schema, and external service status.
