\n\n---\n\n## Tools\n\n9 tools for working with FCC broadband data — block-level availability, geography-level coverage analysis, provider search, and BDC bulk download manifests:\n\n| Tool | Description |\n|:---|:---|\n| `fcc_geocode_block` | Converts a latitude/longitude coordinate to a census block FIPS code (15-digit), county FIPS, county name, state FIPS, state code, and state name. Required prerequisite for `fcc_search_availability`. |\n| `fcc_search_availability` | Queries broadband providers and advertised speeds at a census block, filtered by technology type and speed threshold. The starting point for any address-level broadband lookup. |\n| `fcc_get_coverage_summary` | Returns a broadband coverage summary for a geography — population with zero, one, two, or three-plus providers at a given speed threshold, split by urban/rural and tribal/non-tribal. |\n| `fcc_compare_areas` | Compares broadband coverage metrics across multiple geographies of the same type and returns a ranked table sorted by unserved or underserved population. |\n| `fcc_find_underserved` | Finds geographic areas with limited or no broadband coverage at a given speed threshold, ranked by underserved population. The core tool for BEAD program analysis and broadband equity research. |\n| `fcc_search_providers` | Searches for ISPs by holding company name, filtered by state and technology type. Returns a deduplicated list with `hoconum` identifiers for follow-up calls. |\n| `fcc_get_provider` | Returns a national-level coverage profile for a specific holding company — states served, technologies deployed, and locations covered at each speed tier. |\n| `fcc_list_filing_periods` | Returns available data vintages: Form 477 filing periods (Jun 2015–Jun 2021) and BDC as-of dates (Jun 2022 onward, requires credentials). |\n| `fcc_list_downloads` | Lists downloadable BDC data files for a specific as-of date — availability by state and provider, mobile coverage, and challenge data. Requires BDC API credentials. |\n\n### `fcc_geocode_block`\n\nConvert geographic coordinates to a census block FIPS code for broadband availability lookups.\n\n- Calls the FCC Geo API — no auth required, no rate limit documented\n- Returns 15-digit block FIPS, 5-digit county FIPS, county name, state FIPS, 2-letter state code, and state name\n- Required first step before `fcc_search_availability` — the broadband deployment dataset is indexed by census block, not address\n\n---\n\n### `fcc_search_availability`\n\nQuery which ISPs serve a specific census block and what speeds they advertise.\n\n- Requires a 15-digit census block FIPS; use `fcc_geocode_block` to convert coordinates first\n- Filter by technology code (fiber=50, cable=40–43, DSL=10–12, satellite=60, fixed wireless=70)\n- Filter by minimum advertised download speed in Mbps\n- Filter to consumer-only or business-only service\n- Returns per-provider records with `hoconum`, `techcode`, `maxaddown`, `maxadup`, `consumer`, `business`\n- Coverage is Form 477 data through June 2021 — reflects ISP-reported availability at census block granularity (not address-level)\n\n---\n\n### `fcc_get_coverage_summary`\n\nAnalyze broadband access across any US geography at a given speed threshold.\n\n- Supports seven geography types: `nation`, `state`, `county`, `cd` (congressional district), `place` (census-designated place), `cbsa` (metro area), `tribal`\n- Technology filter: any wired/fixed wireless (`acfosw`), fiber only (`f`), cable (`c`), DSL (`a`), satellite (`s`), fixed wireless (`w`), or combinations\n- Speed thresholds: 0.2, 4, 10, 25 (FCC legacy broadband definition), 100 (BEAD standard), 250, 1000 Mbps\n- Returns population breakdowns: zero providers (unserved), one (no competition), two, three-plus; coverage %, unserved %, competitive %\n- Per-segment breakdown by urban/rural and tribal/non-tribal for equity analysis\n\n---\n\n### `fcc_compare_areas`\n\nRank geographies by broadband access metrics to identify where underservice is worst.\n\n- Compare up to 50 geographies of the same type, or all 50 states + DC via `compare_all_states: true`\n- Sort by unserved population share, raw unserved headcount (useful for BEAD funding allocation), coverage rate, or competitive share\n- Returns a ranked table with per-geography population and coverage metrics\n\n---\n\n### `fcc_find_underserved`\n\nFind the most broadband-underserved areas within a state or nationwide.\n\n- Scope to a specific state or run nationwide (returns top areas only)\n- Geography granularity: county, congressional district, census place, or CBSA\n- Default filter: rural areas only — where underservice is most concentrated\n- Minimum unserved population threshold to exclude very small areas\n- Results ranked by unserved population percentage\n\n---\n\n### `fcc_search_providers`\n\nLook up ISPs by name or state to get `hoconum` identifiers for follow-up queries.\n\n- Case-insensitive partial name match — e.g., `\"Comcast\"`, `\"T-Mobile\"`, `\"Frontier\"`\n- Filter by 2-letter state abbreviation or technology code\n- Returns deduplicated holding companies with `hoconum`, states served, and technology codes\n- Geographic filtering is state-level; sub-state granularity requires cross-referencing block data via `fcc_search_availability`\n- Up to 200 results per call\n\n---\n\n### `fcc_list_filing_periods`\n\nDiscover valid data vintages before querying download manifests.\n\n- Form 477 periods (Jun 2015–Jun 2021) are hardcoded — always available, no credentials needed\n- BDC as-of dates (Jun 2022 onward) are fetched live from the authenticated API — requires `FCC_BDC_USERNAME` and `FCC_BDC_HASH_VALUE`\n- Call before `fcc_list_downloads` to determine valid `as_of_date` values\n\n---\n\n### `fcc_list_downloads`\n\nList BDC bulk data files available for download for a specific filing period.\n\n- Requires BDC API credentials (`FCC_BDC_USERNAME`, `FCC_BDC_HASH_VALUE`)\n- Filter by data type (availability or challenge), file category, technology type, state, or provider name\n- Returns file metadata — provider, state, technology, record count — plus download URLs\n- Returns file manifests, not file contents; BDC CSVs are large zipped files not suitable for inline API response\n\n## Resources and prompts\n\n| Type | Name | Description |\n|:---|:---|:---|\n| Resource | `fcc-broadband://geography/{type}/{id}/summary` | Broadband coverage summary for a specific geography: provider counts by speed tier, urban/rural split, tribal breakdown. Addressable by type and GEOID. |\n| Resource | `fcc-broadband://providers/list` | List of all Form 477 holding companies with `hoconum` identifiers and names. Reference for resolving `hoconum` before calling `fcc_get_provider`. |\n| Prompt | `broadband_equity_analysis` | Structures a digital divide analysis comparing broadband access across demographic groups — guides chaining with Census and BLS data. Accepts `region` and `focus` (`underserved`, `rural`, `tribal`, `all`). |\n\nAll resource data is also reachable via tools. The `providers/list` resource is derived from the deployment table via `$group` aggregation — use `fcc_search_providers` for filtered lookups.\n\n## Features\n\nBuilt on [`@cyanheads/mcp-ts-core`](https://www.npmjs.com/package/@cyanheads/mcp-ts-core):\n\n- Declarative tool, resource, and prompt definitions — single file per primitive, framework handles registration and validation\n- Unified error handling — handlers throw, framework catches, classifies, and formats\n- Pluggable auth: `none`, `jwt`, `oauth`\n- Swappable storage backends: `in-memory`, `filesystem`, `Supabase`, `Cloudflare KV/R2/D1`\n- Structured logging with optional OpenTelemetry tracing\n- STDIO and Streamable HTTP transports\n\nFCC broadband-specific:\n\n- Wraps three FCC data sources: Form 477 public data via Socrata (no auth, 2015–2021), BDC Public Data API (authenticated, Jun 2022 onward), and FCC Geo API (no auth)\n- Auth-optional design — BDC tools return a structured `credentials_required` error with setup instructions when credentials are absent; all Form 477 and geocoding tools always work without credentials\n- Area Table aggregation for equity analysis — uses the pre-aggregated geography table (`xvwq-qtaj`) instead of querying the 50M-row deployment table, enabling fast coverage analysis at county and state scale\n- All data is US federal government public domain (17 USC §105) — safe to distribute and cache\n\nAgent-friendly output:\n\n- Structured error contracts on every tool — typed error codes (`block_not_found`, `credentials_required`, `geography_not_found`, `invalid_as_of_date`) with actionable next-step hints so agents can recover without parsing text\n- Per-segment breakdowns in coverage tools — urban/rural and tribal/non-tribal split in `fcc_get_coverage_summary` outputs so agents can target equity analysis without additional queries\n- Two-era data coverage bridged transparently — Form 477 (2015–2021) and BDC (2022–present) exposed through a unified tool surface, with data ceiling documented in tool descriptions so agents can surface limitations accurately\n\n## Getting started\n\n### Public Hosted Instance\n\nA public instance is available at `https://fcc-broadband.caseyjhand.com/mcp` — no installation required. Point any MCP client at it via Streamable HTTP:\n\n```json\n{\n \"mcpServers\": {\n \"fcc-broadband-mcp-server\": {\n \"type\": \"streamable-http\",\n \"url\": \"https://fcc-broadband.caseyjhand.com/mcp\"\n }\n }\n}\n```\n\n### Self-Hosted / Local\n\nAdd the following to your MCP client configuration file.\n\n```json\n{\n \"mcpServers\": {\n \"fcc-broadband-mcp-server\": {\n \"type\": \"stdio\",\n \"command\": \"bunx\",\n \"args\": [\"@cyanheads/fcc-broadband-mcp-server@latest\"],\n \"env\": {\n \"MCP_TRANSPORT_TYPE\": \"stdio\",\n \"MCP_LOG_LEVEL\": \"info\"\n }\n }\n }\n}\n```\n\nOr with npx (no Bun required):\n\n```json\n{\n \"mcpServers\": {\n \"fcc-broadband-mcp-server\": {\n \"type\": \"stdio\",\n \"command\": \"npx\",\n \"args\": [\"-y\", \"@cyanheads/fcc-broadband-mcp-server@latest\"],\n \"env\": {\n \"MCP_TRANSPORT_TYPE\": \"stdio\",\n \"MCP_LOG_LEVEL\": \"info\"\n }\n }\n }\n}\n```\n\nFor Streamable HTTP, set the transport and start the server:\n\n```sh\nMCP_TRANSPORT_TYPE=http MCP_HTTP_PORT=3010 bun run start:http\n# Server listens at http://localhost:3010/mcp\n```\n\n### Prerequisites\n\n- [Bun v1.3.0](https://bun.sh/) or higher (or Node.js v24+).\n- Optional: FCC BDC credentials for `fcc_list_downloads` and BDC filing periods. Generate a token at [broadbandmap.fcc.gov](https://broadbandmap.fcc.gov) under \"Manage API Access\" — no OAuth, manual token generation only.\n- Optional: Socrata app token (`FCC_OPENDATA_APP_TOKEN`) for higher rate limits on Form 477 queries.\n\n### Installation\n\n1. **Clone the repository:**\n\n```sh\ngit clone https://github.com/cyanheads/fcc-broadband-mcp-server.git\n```\n\n2. **Navigate into the directory:**\n\n```sh\ncd fcc-broadband-mcp-server\n```\n\n3. **Install dependencies:**\n\n```sh\nbun install\n```\n\n4. **Configure environment:**\n\n```sh\ncp .env.example .env\n# edit .env and set required vars\n```\n\n## Configuration\n\nAll configuration is validated at startup via Zod schemas in `src/config/`. Key environment variables:\n\n| Variable | Description | Default |\n|:---|:---|:---|\n| `MCP_TRANSPORT_TYPE` | Transport: `stdio` or `http` | `stdio` |\n| `MCP_HTTP_PORT` | HTTP server port | `3010` |\n| `MCP_HTTP_ENDPOINT_PATH` | HTTP endpoint path | `/mcp` |\n| `MCP_PUBLIC_URL` | Public origin override for TLS-terminating reverse-proxy deployments | none |\n| `MCP_AUTH_MODE` | Authentication: `none`, `jwt`, or `oauth` | `none` |\n| `MCP_LOG_LEVEL` | Log level (`debug`, `info`, `warning`, `error`, etc.) | `info` |\n| `LOGS_DIR` | Directory for log files (Node.js only) | `/logs` |\n| `STORAGE_PROVIDER_TYPE` | Storage backend: `in-memory`, `filesystem`, `supabase`, `cloudflare-kv/r2/d1` | `in-memory` |\n| `FCC_BDC_USERNAME` | FCC account email for BDC API. Without this, `fcc_list_downloads` and BDC-era `fcc_list_filing_periods` return a `credentials_required` error. | none |\n| `FCC_BDC_HASH_VALUE` | API token hash from broadbandmap.fcc.gov \"Manage API Access\". Paired with `FCC_BDC_USERNAME`. | none |\n| `FCC_OPENDATA_APP_TOKEN` | Socrata app token. Increases rate limits on Form 477 queries; not required for functionality. | none |\n| `OTEL_ENABLED` | Enable [OpenTelemetry instrumentation](https://github.com/cyanheads/mcp-ts-core/tree/main/docs/telemetry) | `false` |\n\nSee [`.env.example`](https://github.com/cyanheads/fcc-broadband-mcp-server/blob/main/.env.example) for the full list of optional overrides.\n\n## Running the server\n\n### Local development\n\n- **Build and run:**\n\n ```sh\n # One-time build\n bun run rebuild\n\n # Run the built server\n bun run start:stdio\n # or\n bun run start:http\n ```\n\n- **Run checks and tests:**\n\n ```sh\n bun run devcheck # Lint, format, typecheck, security\n bun run test # Vitest test suite\n bun run lint:mcp # Validate MCP definitions against spec\n ```\n\n### Docker\n\n```sh\ndocker build -t fcc-broadband-mcp-server .\ndocker run --rm -e MCP_TRANSPORT_TYPE=http -p 3010:3010 fcc-broadband-mcp-server\n```\n\nThe Dockerfile defaults to HTTP transport and stateless session mode, logging to `/var/log/fcc-broadband-mcp-server`. OpenTelemetry peer dependencies are installed by default — build with `--build-arg OTEL_ENABLED=false` to omit them.\n\n## Project structure\n\n| Directory | Purpose |\n|:---|:---|\n| `src/index.ts` | `createApp()` entry point — registers tools, resources, and prompts and inits services. |\n| `src/config` | Server-specific environment variable parsing and validation with Zod. |\n| `src/mcp-server/tools` | Tool definitions (`*.tool.ts`). Nine tools across FCC Open Data, BDC API, and Geo API. |\n| `src/mcp-server/resources` | Resource definitions (`*.resource.ts`). Geography summary and provider list resources. |\n| `src/mcp-server/prompts` | Prompt definitions (`*.prompt.ts`). Broadband equity analysis prompt. |\n| `src/services/open-data` | FCC Open Data Socrata service — Form 477 deployment and area table queries. |\n| `src/services/bdc-api` | BDC Public Data API service — authenticated filing period and download manifest endpoints. |\n| `src/services/geo-api` | FCC Geo API service — lat/lon to census block FIPS conversion. |\n| `tests/` | Unit and integration tests mirroring `src/`. |\n\n## Development guide\n\nSee [`CLAUDE.md`](https://github.com/cyanheads/fcc-broadband-mcp-server/blob/main/CLAUDE.md) for development guidelines and architectural rules. The short version:\n\n- Handlers throw, framework catches — no `try/catch` in tool logic\n- Use `ctx.log` for request-scoped logging, `ctx.state` for tenant-scoped storage\n- Register new tools and resources via the barrels in `src/mcp-server/*/definitions/index.ts`\n- Wrap external API calls: validate raw → normalize to domain type → return output schema; never fabricate missing fields\n- Socrata returns all numeric fields as strings — parse `has_0`, `has_1`, `has_2`, `has_3more`, `maxaddown`, `maxadup` as integers\n\n## Contributing\n\nIssues and pull requests are welcome. Run checks and tests before submitting:\n\n```sh\nbun run devcheck\nbun run test\n```\n\n## License\n\nApache-2.0 — see [LICENSE](https://github.com/cyanheads/fcc-broadband-mcp-server/blob/main/LICENSE) for details.\n","changelogMarkdown","videoKey","requiredSecretsJson","publishedAt","priceCents","trialDays",0,"categoryDisplayName","Data & Analytics","upstream",{"_95":96,"_97":-5,"_98":99,"_100":101,"_102":103},"requiredSecrets",[],"tags",[],"assets",[],"stats",{"_93":80,"_94":80},"ratingAvg","reviewCount","topics",[104,105,106,107,108,109,19,110,111,112,113,114,115,116,117],"license","language","TypeScript","registryName","io.github.cyanheads/fcc-broadband-mcp-server","homepage","https://www.npmjs.com/package/@cyanheads/fcc-broadband-mcp-server","ai-agents","ai-tools","bead","broadband","broadband-equity","census-block","digital-divide","fcc","internet-access","mcp","mcp-server","model-context-protocol","open-data","typescript","ENV",{"_120":121,"_122":123,"_124":125},"ENVIRONMENT","production","TURNSTILE_SITE_KEY","0x4AAAAAAB8-rEI2gNDf_QhU","SENTRY_DSN","https://45fd1229f78089d5c3ee78be128030e1@o4510583261757440.ingest.de.sentry.io/4510584253448272"]
