Production-hosted Model Context Protocol servers run by Capitol AI. Connect them to any MCP client — or to your Capitol org via My Tools — with a single API key.
https://tools-staging-eu-west-1.capitol.ai/<server-name>/mcpUS economic time series from FRED (Federal Reserve Economic Data, St. Louis Fed): search series, get series metadata, and fetch observations (GDP, inflation, interest rates, employment, and 800k+ other series).
https://tools-staging-eu-west-1.capitol.ai/fred-server/mcp
US labor statistics from the Bureau of Labor Statistics (BLS) v2 API: CPI, unemployment, payrolls, earnings, JOLTS, PPI and other official time series.
https://tools-staging-eu-west-1.capitol.ai/bls-server/mcp
Live event discovery from Ticketmaster (Discovery API v2): search concerts, sports, theatre and family events by keyword, location, date and category; get full event details (prices, on-sale dates, seat maps, ticket limits); find venues and artists/teams.
https://tools-staging-eu-west-1.capitol.ai/ticketmaster-server/mcp
US federal contract opportunities and awards from SAM.gov: search active solicitations, pre-solicitations, and sources-sought notices by NAICS/PSC/set-aside/date; fetch a notice's full description text; search awarded contract actions (the FPDS replacement); look up entity registrations by UEI or name. Shares a 1,000-requests/day upstream budget — bulk needs belong on the SAM.gov Data Services daily CSV extract, not this API.
https://tools-staging-eu-west-1.capitol.ai/sam-gov-server/mcp
US federal grant and cooperative-agreement opportunities from Grants.gov: search NOFOs across all 26 granting agencies — including forecasted (pre-solicitation) opportunities — and fetch full opportunity details, eligibility, and award amounts. No upstream key required.
https://tools-staging-eu-west-1.capitol.ai/grants-gov-server/mcp
US federal award history from USASpending.gov (every prime contract and grant back to ~FY2008): search awards by NAICS/PSC/agency/recipient, get award details, profile an agency's spending, and find expiring contracts due for recompete. No key required. Note: DoD awards surface ~90 days late by policy.
https://tools-staging-eu-west-1.capitol.ai/usaspending-server/mcp
Early-signal US federal procurement: agency acquisition forecasts from the Acquisition Gateway Forecast of Contracting Opportunities (planned procurements before solicitation — estimated award date, NAICS, set-aside plan, POC), and SBIR/STTR R&D topics and historical awards from sbir.gov. No keys required. Forecast endpoints are unofficial and forecasts are directional — they slip and get cancelled.
https://tools-staging-eu-west-1.capitol.ai/gov-forecast-server/mcp
eBay seller workflows via the Sell APIs (Inventory, Account, Taxonomy, Fulfillment): account readiness, category/aspect discovery, inventory and offer management, staged or composite listing publish, price/quantity updates, withdraw listings, and read seller orders. Sandbox-first; production mutations require explicit write enablement plus a separate write-authorization header (see src/services/ebay/README.md). Shared-catalog API keys alone do not authorize merchant-account mutations.
https://tools-staging-eu-west-1.capitol.ai/ebay-seller-server/mcp
US demographic, economic, and housing data from the Census Bureau Data API: search variable tables and fetch data from ACS 5-Year (and other datasets — Decennial Census, County Business Patterns, Population Estimates) by geography, down to state/county/tract. Curated shortcuts for common indicators (population, median household income, poverty, housing, education, race/ethnicity).
https://tools-staging-eu-west-1.capitol.ai/census-server/mcp
Curated Capitol capabilities for external agent clients (built for Figma's agent/Make custom MCP connectors): list the org's Capitol workflows, discover and read published data snapshots (live JSON, optionally flattened to {label: value} for design editing), run grounded RAG search over the org's document collections, check workflow run status, trigger allowlisted workflows, save files into Capitol, and compile described processes or data pipelines into UNPUBLISHED workflow drafts for canvas review. Org-scoped via the API key; action tools are additionally gated server-side.
https://tools-staging-eu-west-1.capitol.ai/capitol-connector/mcp
Capitol MCP Gateway (ENG-5304): multi-server MCP endpoint serving curated tool surfaces over Capitol workflows, agents, and data assets. Each registered server gets its own path (/capitol-gateway/{slug}/mcp) and its own API keys; the tool surface is resolved per request from the server's registry projection. Servers are created from the Capitol Settings → MCP Servers page or from platform chat — this catalog entry is the serving engine, not a fixed tool list.
https://tools-staging-eu-west-1.capitol.ai/capitol-gateway/mcp
Maritime chokepoint and port activity from IMF PortWatch (satellite AIS): daily vessel transits by ship type for 28 chokepoints including the Strait of Hormuz, Suez, Bab el-Mandeb and Malacca, compared against the same period a year earlier, plus daily port calls and import/export estimates for ~2,000 ports. No upstream key required.
https://tools-staging-eu-west-1.capitol.ai/portwatch-server/mcp
Live Strait of Hormuz crisis monitor from straits.live: open/closed verdict, daily transits vs. pre-crisis baseline, stranded and AIS-dark vessels, Brent/WTI, war-risk insurance, Lloyd's Joint War Committee listed areas, carrier suspensions, pipeline bypass, the Hormuz crisis index, dated daily briefs and a sourced incident timeline. No upstream key required.
https://tools-staging-eu-west-1.capitol.ai/straits-live-server/mcp
Your own UniFi network, read-only, through the community unifi-mcp-server (v0.7.0, pinned): sites, devices, clients, WLANs, firewall and VPN configuration, and in local mode events, alarms, traffic flows and IPS detections. Bring your own UniFi API key: register with auth type custom_headers and send X-UniFi-API-Key (plus X-UniFi-API-Type, X-UniFi-Host, X-UniFi-Site, X-UniFi-Verify-SSL as needed) next to X-API-Key. Cloud mode (unifi.ui.com) is the default. Nothing here changes the network.
https://tools-staging-eu-west-1.capitol.ai/unifi-server/mcp
Vulnerability intelligence from public sources: CVE details and search from the NVD (CVE API 2.0), CISA's Known Exploited Vulnerabilities catalog, FIRST EPSS exploit-likelihood scores, open-source package vulnerabilities from OSV.dev and the GitHub Advisory Database, plus a tool that ranks a list of CVEs by what to fix first. No upstream key required.
https://tools-staging-eu-west-1.capitol.ai/vuln-intel-server/mcp
Security frameworks in one place: search and read MITRE ATT&CK (Enterprise), D3FEND, CWE, CAPEC, NIST CSF 2.0 and NIST SP 800-53 rev5 (OSCAL), and map between them: ATT&CK techniques to 800-53 controls, CWE to CAPEC to ATT&CK, CSF 2.0 to 800-53, and ATT&CK techniques to D3FEND countermeasures. No upstream key required.
https://tools-staging-eu-west-1.capitol.ai/security-frameworks-server/mcp
Public-company cybersecurity disclosures from SEC EDGAR full-text search: 8-K Item 1.05 material cybersecurity incident reports and 10-K Item 1C cybersecurity risk management sections, filtered by company and date, with the disclosure text pulled from the filing. Follows SEC fair-access rules. No upstream key required.
https://tools-staging-eu-west-1.capitol.ai/sec-cyber-disclosures-server/mcp
Company profiles from Moody's Orbis: search by name and fetch a compact profile (country, city, status, website, NACE code, latest accounts period, operating revenue with its currency and unit, and employees). Needs ORBIS_API_KEY. Each company returned spends the shared quota, so results are capped at five.
https://tools-staging-eu-west-1.capitol.ai/orbis-server/mcp
One key unlocks every server above. Self-serve minting needs a password — ask your Capitol AI contact for one.
Self-serve keys are not enabled in this environment. Contact Capitol AI and we will mint one for you.
Each server speaks MCP over streamable HTTP at https://tools-staging-eu-west-1.capitol.ai/<server-name>/mcp. Authenticate with X-API-Key: <key> or Authorization: Bearer <key>.
In your Capitol install open Settings → My Tools, add a tool with the server URL above, auth type api_key (header X-API-Key), and your key as the secret. The tools become available to your org's agents immediately.
curl -s https://tools-staging-eu-west-1.capitol.ai/fred-server/mcp \
-H 'X-API-Key: YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-H 'Accept: application/json, text/event-stream' \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
