Integrations

​

Popular patterns

• SaaS SSE/HTTP servers for product data (e.g., docs, tickets)
• Local stdio servers for CLIs/databases
• Composite agents with multiple servers (fetch, search, storage)

​

Multi‑server agents

from mcp_eval.catalog import Expect

await session.assert_that(Expect.tools.sequence(["search", "fetch"]))
await session.assert_that(Expect.path.efficiency(expected_tool_sequence=["search","fetch"]))

​

Server discovery and drift

• Use mcp-eval server list -v in CI to detect missing tools.
• Add an Expect.tools.count(tool, >=1) guard to ensure expected calls happen.

​

Security

• Store credentials in CI secrets / local secrets file.
• Avoid writing secrets in mcp.json or DXT.
