Tern MCP server

Tern is a remote MCP server that gives an AI agent 3 tools, among them report_outcome, resolve, submit_mandate. It answers at https://mcp.tern0.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.

Resolve capability gaps: validate native MCPs, search live web, and record unmet demand.

Description as the publisher wrote it.

The 3 tools Tern offers

ToolWhat it does
report_outcomeReport whether a resolver request actually worked and how much agent friction it required.
Inputs: requestId, success, selectedServer, agentSteps, latencyMs, failureReason
resolveResolve a real-world capability request. Search the official MCP Registry, actively validate public candidate MCP tool surfaces, then fall back to live web search when native coverage is weak or absent. Weak Registry matches never suppress
Inputs: task, categoryHint, location, deadline, budget, currency
submit_mandateRecord high-intent demand for a capability an agent wants fulfilled. Supplier contact and spending are not enabled yet.
Inputs: task, categoryHint, location, deadline, maxBudget, currency

Questions about Tern

Is there an official Tern MCP server?

Yes. It is published by tern0.com and served from mcp.tern0.com, the vendor's own domain: https://mcp.tern0.com/mcp.

How many tools does Tern have?

3, as returned by the server's own tools/list on 11 September 2026: report_outcome, resolve, submit_mandate.

It answered our last check on 19 October 2026 in 444 ms. Over 6 checks since 10 September 2026 it answered 6.

How do I add Tern to Cursor?

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.tern0.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.

Does Tern need an API key?

It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

Where this comes from

Publisher: com.tern0. Endpoint host: mcp.tern0.com. ARD identifier: urn:air:com.tern0:mcp:resolver. First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page is inferred from its name. Ranking in Neuronto search is never for sale.
