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 Security63
- 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 3 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
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability76
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 535 tokens (~178/item across 3 items; 3 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 Management7
- Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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
How do I install the agentbuilt MCP server?
agentbuilt is a hosted endpoint at https://agentbuilt.dev/api/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.

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 →
audit_ai_readiness Audit how legible a site is to AI assistants ~146
Free. Fetches a URL and reports how readable it is to AI assistants and agents: whether GPTBot, ClaudeBot, PerplexityBot, Google-Extended and friends are allowed in robots.txt, how much real text survives without JavaScript, what JSON-LD entity types are declared, and whether llms.txt, sitemap.xml and an A2A agent card exist. Returns a score, the individual checks, and concrete fixes. It does NOT tell you whether assistants actually recommend the brand — that requires querying the models, which is the paid audit.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | The site to check, e.g. example.com or https://example.com/pricing |
No output schema declared.
No examples provided.
list_agentbuilt_tools List agentbuilt data tools ~129
Free. Returns the agentbuilt catalog of pay-per-result data tools for AI pipelines — what each one does, when to use it, what it explicitly cannot do, and what it costs. Use this when choosing a tool for extracting YouTube transcripts, Substack archives, Shopify/ACP product feeds, or measuring AI-assistant visibility. Each tool is callable over the Apify API, as an MCP tool, or from n8n, Make and Zapier, using the caller own Apify account.
| Name | Type | Req | Description |
|---|---|---|---|
| task | string | – | Optional plain description of the task, to filter the catalog. |
No output schema declared.
No examples provided.
request_visibility_audit Request a free AI visibility audit ~176
Requests the free human-readable audit: agentbuilt asks real buyer questions to ChatGPT, Perplexity, Gemini and Claude and emails back a report on mention rate, citation rate and which competitors get named instead. Only call this when the person you are acting for has asked for it and has given you their own email address for this purpose. Do not call it speculatively, and do not submit an address that is not theirs.
| Name | Type | Req | Description |
|---|---|---|---|
| brand | string | yes | Brand name as customers say it. |
| consent | boolean | yes | True only if that person asked for this report to be sent to that address. |
| domain | string | yes | Primary website. |
| string | yes | Where to send the report. Must belong to the person requesting it. | |
| notes | string | – | Optional: category, competitors to compare against. |
No output schema declared.
No examples provided.
What is the agentbuilt MCP server?

What tools does the agentbuilt MCP server expose?
agentbuilt exposes 3 tools: audit_ai_readiness, list_agentbuilt_tools, request_visibility_audit. Their descriptions and schemas cost roughly 451 tokens of context every time the server is loaded.
Does the agentbuilt MCP server require authentication?
No. We connected to agentbuilt without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the agentbuilt MCP server still maintained?
agentbuilt 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.
