Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability71
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 875 tokens (~175/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the Oravan MCP server?
Oravan is a hosted endpoint at https://oravan.org/api/mcp/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_bill Get a bill decode ~241
Get the full plain-language decode of a federal bill by slug (e.g. "hr-2701-119") or citation (e.g. "H.R. 2701" - resolves to the most recent Congress on a match). Returns the AI-generated summary (headline, tl;dr, what/who/why/cost - automatically checked before publish and clearly labeled when present), the official status in plain language, an urgency band, sponsor, key dates, the official Congress.gov page, and an act_url to Oravan's on-site call flow. This tool never drafts a phone script - script generation happens only on-site, where the caller reads and can edit the script before dialing; that is not available over this API.
| Name | Type | Req | Description |
|---|---|---|---|
| citation | string | – | Bill citation, e.g. "H.R. 2701" or "S.J.Res. 99". Used only when slug is omitted. |
| locale | string | – | Response language: "en" (default) or "es". |
| slug | string | – | Bill slug, e.g. "hr-2701-119". Takes priority over citation when both are given. |
No output schema declared.
No examples provided.
get_representative Get a representative ~95
Get full details for one member of Congress by bioguide ID (e.g. "W000797"), plus their 5 most recently active sponsored bills. Facts only: no scorecards, ratings, or vote grades.
| Name | Type | Req | Description |
|---|---|---|---|
| bioguide | string | yes | Bioguide ID, e.g. "W000797". |
| locale | string | – | Response language: "en" (default) or "es". |
No output schema declared.
No examples provided.
lookup_representatives Look up representatives by ZIP ~208
Look up a person's U.S. House member and two Senators by 5-digit ZIP code. Returns each member's name, party, phone, official website, portrait URL, and district office phone numbers - the number a constituent should actually call. Some ZIP codes span more than one congressional district (needs_address: true, all candidate districts returned); this tool does not perform address-level refinement itself in this release - point the person to the response's reps_url, where a stateless, unlogged Census-geocoder proxy narrows it to a single district from a street address that Oravan never stores. When a House seat currently has no member, `vacancies` lists the empty seat(s) (state + district) explicitly - the departed member is never returned as if still serving, and no election timeline is implied.
| Name | Type | Req | Description |
|---|---|---|---|
| locale | string | – | Response language: "en" (default) or "es". |
| zip | string | yes | 5-digit U.S. ZIP code. |
No output schema declared.
No examples provided.
search_bills Search bills ~150
Search Oravan's bilingual federal bill corpus by free-text query, issue topic, status, or active-only. Returns short teasers (headline, status, urgency) for matching bills, most urgent first.
| Name | Type | Req | Description |
|---|---|---|---|
| active_only | boolean | – | Exclude signed/vetoed (terminal) bills when true. |
| limit | integer | – | Max results (default 20, max 50). |
| locale | string | – | Response language: "en" (default) or "es". |
| query | string | – | Free-text search over the bill title and plain-language summary. |
| status | string | – | Bill status to filter to. |
| topic | string | – | One of the 12 issue categories. |
No output schema declared.
No examples provided.
whats_moving What's moving in Congress ~181
What's moving in Congress recently: active, plain-language-decoded bills that cleared Oravan's 'act now' urgency bar within the last N days (default 7), optionally filtered by topic. Returns an honest empty list with quiet_week: true when nothing has cleared the bar - this tool never pads the list to look busier than Congress actually is this week. If the list is empty because Oravan's own data sync looks stale rather than Congress being quiet, data_stale is set instead so that distinction is never lost.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | – | Lookback window in days (default 7). |
| limit | integer | – | Max results (default 10, max 50). |
| locale | string | – | Response language: "en" (default) or "es". |
| topic | string | – | One of the 12 issue categories. |

What is the Oravan MCP server?
Oravan is an MCP server listed in the public MCP registry as org.oravan/mcp. Nonpartisan U.S. Congress data: bill decodes, rep lookup, bilingual EN/ES, read-only, no accounts. This page covers its hosted endpoint (https://oravan.org/api/mcp/mcp).
Is the Oravan MCP server safe to use?
Oravan scores 80 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Oravan MCP server expose?
Oravan exposes 5 tools: lookup_representatives, get_bill, search_bills, whats_moving, get_representative. Their descriptions and schemas cost roughly 875 tokens of context every time the server is loaded.
Does the Oravan MCP server require authentication?
No. We connected to Oravan without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Oravan MCP server still maintained?
Oravan is still listed as active in the MCP registry. We last reached this channel on 22 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
