• search_datanexus_tools

  DataNexus MCP

  Find the right DataNexus tool by describing your task in plain English. Read-only. No side effects. Call this before any other DataNexus tool to reduce context load from 40000 to 800 tokens. query: Plain English description of your task e.g. check if a Python package has CVEs or look up a UK charity by name. Required. domain: Restrict results to one sub-server: nonprofit, security, compliance, domain, legal, govcon, or regulatory. Optional. Returns matching tool names and parameter hints you can call directly. Do not call this recursively or to validate results — use validate_tool_output for that. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="search_datanexus_tools", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

• execute_code

  L&T MCP

  IMPORTANT: You MUST call this tool to generate any file. Do NOT write code as text. Do NOT tell the user to run code themselves. ALWAYS pass the code to THIS tool and return the download_url to the user. Execute Python code in an isolated Jupyter kernel and return output text + any generated files as base64 and download URLs. YOU MUST USE THIS TOOL when user asks for: - PPT / presentation / slides / deck → use python-pptx, call this tool - PDF / document / report → use reportlab, call this tool - Chart / graph / plot / visualization → use matplotlib, call this tool - Excel / spreadsheet → use openpyxl, call this tool - Word document → use python-docx, call this tool - ANY file generation task → call this tool WORKFLOW — follow exactly: 1. Write the complete Python code 2. Call THIS tool with that code 3. Get back download_url from the result files list 4. Show download_url to user as a clickable link NEVER skip step 2. NEVER output code as text to the user. Pre-installed packages (no pip install needed): python-pptx → PowerPoint presentations reportlab → PDF creation matplotlib → charts and graphs pandas → data analysis numpy → numerical computing python-docx → Word documents openpyxl → Excel files plotly → interactive charts seaborn → statistical charts Pillow → image processing pypdf → read/merge/split PDFs pdfplumber → extract text and tables from PDFs File saving rules — MUST follow: Save ALL files to current directory — NO path prefix prs.save("presentation.pptx") ← PowerPoint plt.savefig("chart.png", dpi=150) ← matplotlib chart df.to_excel("report.xlsx") ← Excel Always print() the filename after saving

• check_french_regulator_alerts

  Sirenic

  French financial regulator (AMF) alerts and registers: screen a name against the official AMF blacklists (unauthorized investment websites, scams, AMF impersonation) and look up PSAN crypto-provider registrations and licensed asset-management companies (SGP) by name or SIREN. Use before trusting an investment site, a crypto provider or an asset manager operating in France. Official AMF open data, refreshed daily. Paid via x402 ($0.01 in USDC or EURC).

Uses OSV.dev for vulnerability lookup, Redis for persistence with 90-day TTL. Supports CycloneDX 1.4/1.5 and SPDX 2.3 JSON. Input size limit: 500 KB. Returns go_no_go signal on register; new_findings on check. Rate limit: 10/minute. No auth required. For DevSecOps teams monitoring production dependency exposure.

• tvm_solve

  mcp

  Use this when you have four of the five time-value-of-money variables (N periods, I/Y annual rate percent, PV, PMT, FV) and need the fifth - annuity, loan, or investment problems - instead of solving the equation by hand. Solving for I/Y uses Newton-Raphson (no closed form). Supports compoundingPerYear and annuityDue (payments at the beginning of each period). Follows the cash-flow sign convention (outflows negative). Deterministic: same input, same output. Example: solveFor 'fv', n 120, iy 6, pv -10000, pmt -200, compoundingPerYear 12 -> result 50969.84. result holds the solved value; iy is rounded to 4 decimals, all others to 2.

• rack_capacity

  calc.engineer

  Quick rack space and weight sizing calculator for homelab and small data center racks. Enter your devices with their height in rack units, weight, and wattage to get total utilization, remaining free space, weight totals in lbs and kg, and recommended PDU count based on the NEC 80% continuous load rule (1920W per 20A/120V PDU). Estimates cable management overhead at 2U per 10U of installed gear. Outputs total_watts that chains into power_cost and cooling_btu for full infrastructure planning.

  Connector

• pcb_thermal

  calc.engineer

  Estimate PCB component temperatures by solving a thermal resistance network (thermal↔electrical analogy) with the built-in MNA solver. Each component gets a junction node (package θjb from a typical-datasheet table), a local board node coupled to its neighbours through in-plane FR4/copper conduction, and convection to ambient. Computes per-component junction and case temperatures, board extremes, and flags max-junction violations. Runs instantly in-worker; mesh-level CFD via container backend is planned.

• brightdata_unlock

  Bright Data

  Fetch any URL through Bright Data Web Unlocker — rotating residential proxies with automatic anti-bot bypass and CAPTCHA solving, built for the hardest-to-scrape sites (Cloudflare, PerimeterX, Akamai fronted). Returns the page content with status and length; large pages are truncated. Calls proxy the fetch synchronously and can take 10-30 seconds. BYOK: Bright Data API token via _apiKey + a Web Unlocker zone configured in your dashboard (first zone is auto-named "web_unlocker1"); pay-per-request pricing on the Bright Data side. Example: brightdata_unlock({ url: "https://example.com", _apiKey: "your-brightdata-token" })

  Owl Group Trading — Indicator Code

  Return the verified implementation of an Owl Group Trading indicator in a given platform. Args: slug (e.g. 'rl10', 'dragon', 'river-flood-plain') and platform (e.g. 'python', 'javascript'). Returns the commented source code, the verification proof (real Python-vs-JS parity), the summary, and the page URL. Call list_indicators first to see valid slugs and platforms.

• submit_request

  runcomfy-mcp

  Submit an async inference request to a deployment. Backs ``POST /prod/v1/deployments/{deployment_id}/inference``. Args: deployment_id: Target deployment. overrides: Partial graph keyed by node_id, e.g. ``{"6": {"inputs": {"text": "a cat"}}}``. Use ``get_deployment(include_payload=true)`` to discover node IDs and input names. workflow_api_json: Advanced — run a different workflow without updating the deployment. Omit ``overrides`` in this mode. extra_data: E.g. ``{"api_key_comfy_org": "comfyui-..."}`` for ComfyUI Core API nodes. webhook_url: Push-based updates instead of polling. webhook_intermediate_status: Fire webhooks on every status change, not just terminal. wait_for_completion: If true, poll until done and return the result inline. timeout_seconds: Max wait when wait_for_completion=true. File inputs: pass a public HTTPS URL or Base64 data URI directly in the overrides value, e.g. ``{"189": {"inputs": {"image": "https://example.com/photo.jpg"}}}`` or ``{"189": {"inputs": {"image": "data:image/jpeg;base64,/9j..."}}}``.

• methodist_traverse

  OpenArx

  Multi-hop traversal from a claim over typed relation edges of ONE class. Default walks the epistemic §7 edges transitively (support/extend/qualify/refute/background/shared_evidence/same_as); relation_class="engineering" walks the ENG_DEPENDS_ON/ENG_SATISFIES dependency graph. direction="out" = forward (dependencies / cited); "in" = reverse (impact set — who depends on this). ★ This `direction` is the TRAVERSAL direction of the read and has NOTHING to do with the `direction` FIELD on a relation record — different thing, same name. Do not copy in/out into a record. For engineering it also returns cycle_detected (start claim in a dependency cycle). Class label-spaces are disjoint — a §7 walk never crosses into engineering edges and vice versa.

• get_institutions_leaderboards
