Freshness
Last checked 2/22/2026
Best For
Contract is available with explicit auth and schema references.
Not Ideal For
mcp-echo-sse is not ideal for teams that need stronger public trust telemetry, lower setup complexity, or more explicit contract coverage before production rollout.

Summary
Published capability contract available. No trust telemetry is available yet. Last updated 2/24/2026.
Setup snapshot
git clone https://github.com/jasonmadigan/mcp-echo-sse.git- 1
Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.
- 2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Testing with cURL
# Connect to SSE endpoint and get session ID
curl -N -H "Accept: text/event-stream" http://localhost:3000/sse
# You'll see something like:
# event: endpoint
# data: /messages?sessionId=abc123-def456-...
# Initialize the connection (use your session ID)
