name_project
Two-phase naming engine. Call without candidates to receive generation instructions for YOUR model (you generate the names). Call again with candidates[] to get anti-slop scoring, ranking, and live availability checks (domains, socials, npm). Modes: brief (describe it), auto (I analyze the current workspace), from_name (find domains/variants for a name), from_domain (fit a found domain to a project).
search_domain
Search for domain availability and pricing across multiple TLDs.
Returns:
- Availability status for each domain
- Pricing (first year and renewal) when Pricing API is configured
- Whether WHOIS privacy is included
- Human-readable insights and next steps
Examples:
- search_domain("vibecoding") → checks vibecoding.com, .io, .dev
- search_domain("myapp", ["com", "io"]) → checks specific TLDs
bulk_search
Check availability for multiple domain names at once.
Efficiently searches up to 100 domains in parallel with rate limiting.

analyze_project
Analyze a local project or GitHub repository to extract context for domain suggestions.
This tool scans project manifest files (package.json, pyproject.toml, Cargo.toml, go.mod)
and README files to understand your project, then generates relevant domain name suggestions.
**Use Cases:**
1. Find a domain for your existing codebase
2. Get domain ideas that match your project's identity
3. Analyze any GitHub repo for branding inspiration
**Supported Projects:**
- Node.js (package.json)
- Python (pyproject.toml, setup.py)
- Rust (Cargo.toml)
- Go (go.mod)
- Any project with README.md
**Examples:**
- analyze_project("/path/to/my-app") → Analyzes local project
- analyze_project("https://github.com/vercel/next.js") → Analyzes GitHub repo
- analyze_project("/my-project", suggest_domains=true, style="short") → Short brandable names
hunt_domains
Find valuable domains for investment opportunities.
Scans Sedo auctions, generates pattern-based candidates, and calculates investment scores
based on length, TLD value, keyword matches, and pronounceability.
**Investment Score Factors:**
- Length: Shorter = higher score (3-4 chars = +25 points)
- TLD Value: .com = +25, .io/.ai = +15, .co = +12
- Keyword Match: +5 per keyword found in domain
- Pronounceability: Good vowel ratio = +10
- Aftermarket Price: Lower prices get bonus points
**Pattern Types:**
- `short`: 3-5 character pronounceable patterns (CVC, CVCV)
- `dictionary`: Common words that make good domains
- `brandable`: Keyword + modern suffixes (-ly, -ify, -io)
- `acronym`: Abbreviations from multiple keywords
- `numeric`: Keyword + numbers (7, 24, 365)
**Examples:**
- hunt_domains(keywords=["ai", "chat"]) → Find AI/chat themed domains
- hunt_domains(max_length=5, tlds=["com"]) → Ultra-short .com domains
- hunt_domains(max_aftermarket_price=500) → Sedo auctions under $500
- hunt_domains(patterns=["short"], score_threshold=60) → High-scoring short domains
expiring_domains
Find domains that are about to expire and may become available soon.
Monitors the federated negative cache for domains approaching their expiration date.
Useful for domain investors and those watching specific domains.
Requires NEGATIVE_CACHE_URL to be configured.
Examples:
- expiring_domains(days=30) → Domains expiring in the next 30 days
- expiring_domains(tlds=["com"], days=7) → .com domains expiring within a week
- expiring_domains(keywords="ai") → AI-related domains expiring soon
ai_health
Check health status of AI inference services.
Returns status of:
- VPS Qwen (self-hosted llama.cpp)
- Together.ai (cloud fallback)
- Semantic Engine (offline, always available)
- Circuit breaker states
- Adaptive concurrency limits
Use when:
- AI suggestions are slow or failing
- Diagnosing which AI source is being used
- Monitoring inference infrastructure
Firecrawl MCP Server Tools (25)
firecrawl_scrape
Retrieve and extract content from one supplied URL through Firecrawl. Use this when the request identifies a page and needs its content or defined fields. It can return markdown, HTML, links, screenshots, branding data, a targeted answer, or JSON matching a supplied schema; JSON is useful when the requested result has defined fields, while markdown preserves readable page content.
This tool operates on a known page. For a set of pages use `firecrawl_crawl`, and to discover page URLs use `firecrawl_map` or `firecrawl_search`. Options include JavaScript render delay, cache age, main-content filtering, PII redaction, and lockdown cache-only retrieval. Browser actions may change the live page when interactive actions are enabled.
Firecrawl may reuse recently indexed content instead of refetching the page, and the reuse window varies by domain. Set `maxAge: 0` to force a live fetch, or a smaller `maxAge` to bound how stale reused content may be. A successful response does not by itself confirm that the state it describes is still current.
Returns the selected content formats and page metadata.
firecrawl_map
Enumerate URLs indexed under one website through Firecrawl without fetching each page's content. Use this when the request asks for a site's URL inventory, when several relevant pages must be located, or when the desired page URL is unknown. An optional `search` term narrows the URL list, while sitemap, subdomain, query-parameter, and result-limit options control coverage.
Returns matching URLs rather than page bodies. Retrieve one page with `firecrawl_scrape`; collect content across multiple pages with `firecrawl_crawl`.
firecrawl_search
Search web, news, or image sources and return ranked results. Operators include quoted phrases, `-term`, `site:host`, `inurl:term`, `intitle:term`, and `related:host`; the set is non-exhaustive. `includeDomains` and `excludeDomains` are mutually exclusive hostname filters; categories limit results to GitHub, research, PDF, or developer sources.
For a programming question, add `categories: ["developer"]`. It searches an index of GitHub issues, merged pull requests, repository READMEs, and curated documentation sites, and returns the hits in `data.developer` beside the web results.
`categories: ["research"]` restricts these web results to research-affiliated websites and returns page snippets. The `firecrawl_research_*` tools are a separate surface that searches paper abstracts and full text across biomedical (PubMed, bioRxiv, medRxiv) and arXiv literature.
`scrapeOptions` can attach extracted page content; pages fetched this way use a fixed reuse window and ignore `maxAge`, so use `firecrawl_scrape` when a live fetch is required. Returns source-type result groups and usage metadata. Authenticated responses can include an `id` for optional search feedback.
firecrawl_crawl
Start a multi-page crawl at a website URL, poll it to a terminal state, and return the final status and collected data. Scope can be bounded with include/exclude paths, depth, page limit, subdomain/external-link controls, sitemap handling, delay, and scrape options.
Crawl results can be large; use conservative limits when full-site coverage is unnecessary. Webhooks and interactive scrape actions are unavailable in safe mode. Returns the crawl ID, status, and page data.
firecrawl_check_crawl_status
Retrieve the current status, progress, and available results for an existing crawl ID. This only reads Firecrawl job state and does not start or modify the crawl.
firecrawl_extract
Deprecated compatibility entry point. Use firecrawl_scrape once per known URL with formats: ["json"] and jsonOptions containing the prompt and schema. Use firecrawl_search or firecrawl_agent before Scrape when URLs are not known.
firecrawl_agent
Start an asynchronous web research job from a prompt, optional seed URLs, and an optional JSON schema. Use this for a requested synthesis across multiple sources when the task can wait for asynchronous completion. The agent can search, navigate, read pages, and assemble a structured result.
This call returns only a job ID, not the research result. Read the job with `firecrawl_agent_status` until it reaches `completed` or `failed`; research commonly takes several minutes. If the job cannot finish within the task's available time, `firecrawl_search` and `firecrawl_scrape` can gather evidence synchronously.
firecrawl_agent_status
Retrieve progress or final results for a `firecrawl_agent` job ID. A `processing` response is non-terminal and does not contain the final research result. Check again after 15–30 seconds until the status is `completed` or `failed`; complex jobs can take several minutes. If the job cannot finish within the task's available time, use `firecrawl_search` and `firecrawl_scrape` to complete the requested output.
Returns job status, progress information, and result data when completed.
firecrawl_interact
Open or reuse a live browser session to navigate a page, click controls, fill fields, or run browser code. Provide either `url` or `scrapeId`, and either a natural-language `prompt` or executable `code`; code can run as Bash, Python, or Node with a bounded timeout.
This acts on the live site, so actions such as form submission can create persistent external side effects. Returns execution output, stdout/stderr, exit status, and session viewing URLs.
firecrawl_interact_stop
Stop the live interact session associated with a `scrapeId` and release its resources. Returns a success confirmation.
firecrawl_parse
Parse one supported document into markdown, HTML, links, summary, targeted answers, or JSON matching a schema. Supported inputs include common HTML, PDF, Word, RTF, OpenDocument, and spreadsheet files; PDF parsing can be bounded with `pdfOptions.maxPages`.
Local MCP reads `filePath` from the server filesystem. Hosted MCP uses two calls: first provide `filePath` to receive upload instructions, upload locally, then call again with the returned `uploadRef`; do not send both fields together. Remote web URLs belong in `firecrawl_scrape`.
Set `redactPII` to request redaction of personally identifiable information in the returned content. `zeroDataRetention` requires an eligible authenticated account; omit it for anonymous keyless use. Returns upload instructions for hosted phase one or parsed document content for the final call.
firecrawl_monitor_create
Create a recurring scrape, crawl, or search monitor that compares each check with its retained predecessor. The simple form accepts `page`/`pages` or `queries` plus a plain-language `goal`; the advanced `body` form controls targets, schedule, change-tracking formats, judging, retention, webhook, and notifications.
In the simple form, a `goal` is required. If `queries` contains one or more non-empty values and is supplied with `page`/`pages`, `queries` create the search target and page targets are ignored. A monitor schedules future network checks and can send configured email or webhook notifications. Returns the created monitor.
