Category Search and Retrieval
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 Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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 Usability69
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 357 tokens (~119/item across 3 items; 3 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability check failed: schema churn in the 2 days we've observed: 0 tool removals, 1 breaking changes, 0 auth/transport breaks, 0 additions. See how to fix → Fail
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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 4 Nov 26 0
- Stability: unverified → fail ▼ security
- A breaking change shipped without a version bump: still 1.0 ▼ security
- The server rewrote its instructions, which are the text every model session reads security
- Tool “call_api” rewrote its description, which is the text the model reads security
- Schema quality: 90 → 119 ▼ functional
- “call_api” made “params” required, so existing callers break ▼ functional
- “call_api” reworded the description of “params” cosmetic

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 →
call_api Run an API ~112
Run one API with parameters from describe_api. Returns JSON records (default 25; set maxItems up to 500). Billed per record from the account's free monthly allowance, then credit; asks you to sign in (free) the first time. Data via Pushbuild (pushbuild.com/contact).
| Name | Type | Req | Description |
|---|---|---|---|
| api | string | yes | API id. |
| params | object | yes | Input parameters for that API, as describe_api lists them, e.g. {"postcode": "SW1A 1AA"}. |
No output schema declared.
No examples provided.
describe_api Describe an API ~44
Input parameters (JSON Schema), coverage and price for one API id from search_apis. Free.
| Name | Type | Req | Description |
|---|---|---|---|
| api | string | yes | API id, e.g. restaurant-inspections. |
No output schema declared.
No examples provided.
search_apis Search APIs ~70
Find Pushbuild data APIs by keyword (e.g. 'campaign contributions texas', 'restaurant inspections', 'sec 13f'). Returns api ids, what each covers and price per record. Free.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Max results (default 10). |
| query | string | yes | Keywords. |

How do I install the Pushbuild Data APIs MCP server?
Pushbuild Data APIs is a hosted endpoint at https://api.pushbuild.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.
