Synap402 MCP Server
Lets an agent list open models, check per-token prices, estimate cost and run completions
Synap402 is a Developer Tools MCP (Model Context Protocol) server: Lets an agent list open models, check per-token prices, estimate cost and run completions. It is Apache-2.0-licensed and available as a hosted endpoint, so it works with no local install. It exposes 4 tools including synap_chat_completion, synap_list_models, synap_get_model, synap_estimate_cost. Listed on MCP Collection since November 2026.
About Synap402
Remote MCP server for Synap402, an OpenAI-compatible inference API for open models (Qwen, gpt-oss, Gemma, GLM, DeepSeek). Tools: synap_list_models (models with live per-token prices), synap_get_model, synap_estimate_cost (cost of a request before running it) and synap_chat_completion. Listing models and estimating cost need no key; chat completion takes a Synap402 API key as a Bearer token. Hosted endpoint (Streamable HTTP): https://synap402.com/mcp. Local: npx -y synap-mcp.

Synap402 tools (4)
Read from the live server on Nov 13, 2026. These are the tools your AI assistant can call once connected.
synap_chat_completion- Send a conversation to a model on Synap, Linkrra's OpenAI-compatible inference API, and get the model's reply. Use this when you need text generated, code written or a question answered by one of the open models Synap serves. This is the on
synap_list_models- List the models Synap serves right now, each with its price per million tokens, context window and what it is good at. Use this to choose a model id before calling synap_chat_completion, or to compare prices. Free, read-only, no API key nee
synap_get_model- Return the complete catalogue record for one Synap model: pricing, context and output limits, supported parameters, quantisation, data-retention policy and readiness. Use this after synap_list_models when you need details the summary leaves
synap_estimate_cost- Work out what a chat completion would cost on Synap from token counts, using the live price list. Use this before synap_chat_completion when budget matters, or to compare models for a job. Free, read-only, needs no API key and runs no model
How to connect Synap402 to Claude, Cursor or VS Code
Synap402 runs as a hosted remote MCP server at https://synap402.com/mcp. Add that URL to your MCP client's config (Claude Code, Cursor, Windsurf or VS Code) and the tools appear immediately, no install required.
