Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 572 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability74
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 20780 tokens (~36/item across 572 items; 572 tools + 0 resources), lean.Pass
- 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 Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (96% of tools); any adoption earns full credit.Pass
Tool Safety50
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 9 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "truncate" implies "truncate" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- Manipulation not yet verified: only 564 of 573 captured unit(s) of tool text has been judged so far, so we will not certify text no model has read as clean.Unverified
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the TinyFn MCP server?
TinyFn is a hosted endpoint at https://api.tinyfn.io/mcp/all/, 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.

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 →

What is the TinyFn MCP server?
TinyFn is an MCP server listed in the public MCP registry as io.tinyfn/tinyfn. 500+ deterministic tools for AI agents: math, conversion, validation, hashing, encoding, date/time. This page covers its hosted endpoint (https://api.tinyfn.io/mcp/all/).
Is the TinyFn MCP server safe to use?
TinyFn scores 75 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 TinyFn MCP server expose?
TinyFn exposes 572 tools: is_even, is_odd, is_prime, is_positive, is_negative, and 567 more. Their descriptions and schemas cost roughly 20,637 tokens of context every time the server is loaded.
Does the TinyFn MCP server require authentication?
No. We connected to TinyFn without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the TinyFn MCP server still maintained?
TinyFn is still listed as active in the MCP registry. We last reached this channel on 26 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
