mcp-registry/io.github.imagiever-ar/a2a-artifact-handoff · v1.29.0
As of 2026-10-19 01:13 UTC, the Imagiever Ar A2a Artifact Handoff MCP server is down with a Glimind reliability score of 38/100 (grade F). Over the last 30 days it answered 99.4% of Glimind's liveness checks. It had 4 outages in 90 days, with a median recovery of 181 hours.
Compiles source-agent outputs into validated, receiver-ready handoff packages.

The endpoint did not complete an MCP handshake.
Check the URL, TLS certificate and that the server answers a JSON-RPC "initialize" POST. How to fix →
1 tool definition(s) exceed ~1,200 tokens each (largest: compile_handoff, ~1,468).
Move long reference material out of descriptions (link a doc or expose a resource), drop repeated examples, and collapse large enums. Trimming these to ~600 tokens saves ~868 tokens every session. How to fix →
10 parameter(s) across 3 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 →
3 of 3 tool(s) carry no readOnlyHint/destructiveHint annotations.
Annotate read-only tools with {"readOnlyHint": true}. Agents and gateways can then run them without a confirmation prompt, and route around destructive ones. How to fix →
Handshake + tools/list takes ~1,918 ms.
Serve tools/list from memory, keep the process warm, and host close to your users. Every new agent session pays this before its first call.

Imagiever Ar A2a Artifact Handoff MCP server advertises 3 tools, including compile_handoff, inspect_handoff, prepare_artifact.

Glimind scanned all 3 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.
