Endpoint Security80
Transport & Reachability100
Schema Quality & AI Usability73
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 980 tokens (~122/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage85
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 48% of tool parameters carry a description.Partial
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the Sourcey MCP server?

Sourcey is a hosted endpoint at https://mcp.sourcey.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 8 exposed · ~885 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the Sourcey MCP server?

Sourcey is an MCP server listed in the public MCP registry as com.sourcey/sourcey. Find and compare startup credits and deals with eligibility checks and exact evidence. This page covers its hosted endpoint (https://mcp.sourcey.com/mcp).

Is the Sourcey MCP server safe to use?

Sourcey scores 86 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Sourcey MCP server expose?

Sourcey exposes 8 tools: search_offers, compare_offers, inspect_evidence, get_changes, search_readiness, and 3 more. Their descriptions and schemas cost roughly 885 tokens of context every time the server is loaded.

Does the Sourcey MCP server require authentication?

No. We connected to Sourcey without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Sourcey MCP server still maintained?

Sourcey is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
