ClaudeR RStudio MCP Server tools 41
execute_rExecute R code and return the outputexecute_r_with_plotExecute R code that generates a plotget_r_infoGet a summary of the R environment. Returns package count (not full list), first 20 variables, and R version. Use requireNamespace('pkg') to check for specific packages.get_active_documentRead the focused RStudio editor BUFFER (not the file on disk). Returns the content, the document path, and 'unsaved_changes' telling you whether the buffer differs from disk. Use this as the source of truth while editing; read_file reports the DISK state, which will be stale until the edit is saved. Errors loudly if no document is open or focused.modify_code_sectionRegex find-and-replace in an RStudio editor document. Saves to disk by default (save=false stages the edit in the buffer only). Pass 'path' to target a specific file instead of whatever happens to be focused. The replacement may change the number of lines. Returns 'saved_to_disk' so you know whether read_file will reflect the change.insert_textInsert text into an RStudio editor document at the cursor, or at a given line/column. Saves to disk by default (save=false leaves it unsaved in the buffer). Pass 'path' to target a specific file rather than whatever is focused.suggest_editPropose an edit for the user to APPROVE before it is applied, instead of writing it directly. Uses rstudioapi::showEditSuggestion() when the RStudio build provides it; otherwise stages the change in the editor buffer and deliberately does NOT save, so the user accepts by saving or rejects with Undo. Use this when the user asked to review changes first. After calling it, STOP and wait for the user's decision.create_task_listCreate a task list for the current analysisupdate_task_statusUpdate the status of a task and optionally add notesclean_error_logClean a ClaudeR session log by removing error blocks and their duplicates. Parses the log, finds errors, checks if a fix follows each error, removes the error blocks and any duplicate code blocks that preceded them. Returns a report of what was found and removed.execute_r_asyncExecute long-running R code in a separate background R process. Returns a job ID immediately and the main session stays fully responsive. Use this for code that may take longer than 25 seconds (e.g., model fitting, simulations, large data processing). TWO MODES: 1. Auto-marshaled (recommended). Pass `inputs` (object names from the main session to copy into the background) and `outputs` (object names the background code creates that should be loaded back into the main session). The tool handles all saveRDS/readRDS plumbing. Inputs are snapshotted at submit time, so changes in the main session after submit do not affect the running job. Outputs are auto-loaded into the main session when get_async_result returns complete. 2. Manual. Omit `inputs` and `outputs` and write self-contained code that uses saveRDS()/readRDS() to pass data in and out yourself. Backwards-compatible with existing patterns. The background process never has access to the main session's environment except via the marshaled `inputs`. Connection objects (DB connections, open file handles) cannot be marshaled. The background process must `library()` any packages it needs. You can continue executing other code with execute_r while the job runs. Use get_async_result to check status when ready.get_async_resultCheck the result of an async R job. Waits ~10 seconds before checking to avoid excessive polling. If the job is still running, call this again.- +29 more on the listing page
Firecrawl MCP Server tools 25
firecrawl_scrapeRetrieve 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_mapEnumerate 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_searchSearch 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_crawlStart 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_statusRetrieve 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_extractDeprecated 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_agentStart 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_statusRetrieve 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_interactOpen 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_stopStop the live interact session associated with a `scrapeId` and release its resources. Returns a success confirmation.firecrawl_parseParse 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_createCreate 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.- +13 more on the listing page
