Third-party server, listed as discovered. Review its source before installing.
1 tool definition(s) exceed ~1,200 tokens each (largest: places.lookup, ~1,909).
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 ~1,309 tokens every session. How to fix →
12 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 →
Handshake + tools/list takes ~1,523 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.
Paste-ready definitions with the problems above fixed. Changes marked verify need a human look. All of them as JSON: /v1/readiness/mcp-registry%2Fio.github.sandeep-antier%2Fabstraxn/fixes

As of 2026-10-25 00:35 UTC, the Sandeep Antier Abstraxn MCP server is up with a Glimind reliability score of 94/100 (grade A). Over the last 30 days it answered 100% of Glimind's liveness checks. It had 6 outages in 90 days, with a median recovery of 3 minutes.
Sandeep Antier Abstraxn MCP server advertises 12 tools, including market.crypto, network.blocknumber, network.gas_info, network.prepare_transfer, network.token_info.
Point your MCP client at this streamable-http endpoint: https://mcp.abstraxn.com/mcp
Glimind scanned all 12 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.
