Basic company lookup

basic_lookup

Read-onlyIdempotent

Public company profile: summary plus firmographics (industry, HQ city/country, founded year, employee count and size range, ticker, LinkedIn/X), each field with source, source_url, checked_at and confidence, from Wikidata, Wikipedia, the company homepage and SEC EDGAR. Unknown fields are null, never guessed. Not a contact or CRM record. Price: $0.10 USDC on Base per call via x402; this MCP call returns payment instructions and the paid HTTP route POST /v1/basic returns the brief. Read-only.

Input Schema

Name	Required	Description	Default
`domain`	No	Optional company website domain without https, for example stripe.com. Improves accuracy and enables the public website crawl.
`company`	Yes	Company name, for example "Stripe".

Output Schema

Name	Required	Description
`tool`	Yes	Tool name.
`result`	No	Paid result: { tool, version, company: { name, domain, summary, summary_source_url, public_page, firmographics: { official_name, industry, hq_city, hq_country, founded_year, employee_count, size_range, ticker, linkedin_url, x_url: each { value, source, source_url, checked_at, confidence } }, entity } }.
`status`	Yes	payment_required: pay the HTTP route with x402 to get the result. ok: result is included.
`message`	Yes	Human-readable summary.
`payment`	No	Payment instructions. MCP tools/call does not charge or run the paid work; call the HTTP route with x402.

TDQS

A4.1/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is known. The description adds critical behavioral context beyond annotations: the per-call price ($0.10 USDC on Base via x402), the two-step MCP-plus-HTTP invocation flow, the data sources (Wikidata, Wikipedia, homepage, SEC EDGAR), the per-field provenance metadata (source, source_url, checked_at, confidence), and the null-not-guessed policy. This is exactly the kind of context annotations cannot convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense and front-loaded, leading with the resource and its fields before moving to provenance, exclusions, payment, and the invocation flow. It is on the longer side but every clause conveys distinct information; a slight trim of the source list would help but nothing is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has an output schema, return values need not be explained, yet the description still usefully summarizes field-level provenance and null handling. The main missing piece is explicit guidance on when to choose this over enriched_lookup or prospect_brief, but for a paid public-data lookup the description is otherwise complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents both parameters with examples and the domain parameter's accuracy benefit. The description does not add parameter-level detail beyond what the schema provides, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific resource (public company profile) and enumerates exactly what it returns (firmographics: industry, HQ city/country, founded year, employee count, ticker, social handles). It explicitly distinguishes from siblings by stating 'Not a contact or CRM record,' separating it from email_lookup and enriched_lookup.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies this is the base-level lookup and hints at richer siblings via 'basic' and 'Not a contact or CRM record,' but never explicitly says when to use this versus enriched_lookup or prospect_brief. It does clearly state payment requirements and the two-step flow (MCP returns payment instructions, POST /v1/basic returns the brief), which is useful guidance but not selection logic.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
