# Allowances API (remote · mcp.allowancesapi.com) U.S. government per diem and overseas allowance rates from GSA, DTMO OCONUS and State DSSR tables. - Trust score: 80/100 (high trust) - Registry status: active - Liveness: live - Owner verified: no - Last scored: 2026-11-06 ## Components - remote · `mcp.allowancesapi.com`: 80/100 (this document), [markdown](https://verifymcp.io/servers/com-allowancesapi-per-diem-allowances/mcp.md), [page](https://verifymcp.io/servers/com-allowancesapi-per-diem-allowances/mcp) ## Channel facts - Endpoint: `https://mcp.allowancesapi.com/mcp` - Transports: `streamable-http` - Auth: `required` - Version: `1.0.0` ## Trust breakdown 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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-11-06. - **Endpoint Security**: 97/100 - The endpoint's TLS certificate is valid, in date, and uses a strong key. - Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. - HTTPS is enforced; there's no plaintext access path. - The HSTS (Strict-Transport-Security) header is present. - DNSSEC check failed: this domain isn't protected by DNSSEC. - The authorisation server supports Client ID Metadata Documents, the current MCP client-registration mechanism. - **Transport & Reachability**: 100/100 - Verified streamable-http transport via a live MCP handshake. - **Schema Quality & AI Usability**: 67/100 - AI-judged instruction clarity (excellent). - Context-footprint check failed: tool/resource definitions use about 8889 tokens (~206/item across 43 items; 43 tools + 0 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 17/100 - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses. - **Tool Coverage**: 98/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 94% of tool parameters carry a description. - **Tool Safety**: 75/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - 0 of 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "search_opm_pay" implies "pay" and declares readOnlyHint instead, contradicting what its own name says it does. - An AI judge read all 44 captured unit(s) of tool text and found none that tries to manipulate the model reading it. - **Capabilities**: 100/100 - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28. ## Install ### How do I install the Allowances API MCP server? Allowances API is a hosted endpoint at https://mcp.allowancesapi.com/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. ### Claude ```bash claude mcp add --transport http com-allowancesapi-per-diem-allowances 'https://mcp.allowancesapi.com/mcp' ``` ### Cursor ```json { "mcpServers": { "com-allowancesapi-per-diem-allowances": { "url": "https://mcp.allowancesapi.com/mcp" } } } ``` ### VS Code ```json { "servers": { "com-allowancesapi-per-diem-allowances": { "type": "http", "url": "https://mcp.allowancesapi.com/mcp" } } } ``` ### Codex ```toml [mcp_servers.com-allowancesapi-per-diem-allowances] url = "https://mcp.allowancesapi.com/mcp" ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "com-allowancesapi-per-diem-allowances": { "type": "remote", "url": "https://mcp.allowancesapi.com/mcp", "enabled": true } } } ``` ### OpenClaw ```bash openclaw mcp add com-allowancesapi-per-diem-allowances --url 'https://mcp.allowancesapi.com/mcp' --transport streamable-http ``` ### Hermes ```yaml mcp_servers: com-allowancesapi-per-diem-allowances: url: "https://mcp.allowancesapi.com/mcp" ``` ### Netclaw ```json { "McpServers": { "com-allowancesapi-per-diem-allowances": { "Transport": "http", "Url": "https://mcp.allowancesapi.com/mcp" } } } ``` ### Vellum ```bash assistant mcp add com-allowancesapi-per-diem-allowances -t streamable-http -u 'https://mcp.allowancesapi.com/mcp' ``` ### Other ```json { "mcpServers": { "com-allowancesapi-per-diem-allowances": { "type": "http", "url": "https://mcp.allowancesapi.com/mcp" } } } ``` The mcpServers block is a cross-client convention.

Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes. ### 2026-11-02 (score 63, 0) - [functional improvement] Stability: unverified → 0.03 ### 2026-11-01 (score 63) First indexed and scored. ## MCP tools (43) ### `get_allowances` (~324 tokens) DSSR allowances by country Returns State Department (DSSR) allowance rates for every post in a country: cost-of-living (COLA), hardship differential, living quarters (LQA), danger pay and education allowances, plus each post's per diem, in force today or on `date`. `type` limits the result to some allowances. For one post use get_allowances_by_location or get_allowances_by_postcode; for Department of Defense rates use the DTMO tools. Input parameters: - `country_iso_code` (string, required): ISO 3166-1 alpha-2 country code, e.g. PG for Papua New Guinea; ZZ stands for 'Other Foreign Localities', not a country. Resolve a country name to its code with get_countries (q=name). - `date`: The day the rates must be in force, YYYY-MM-DD; today when omitted. Plan limits: Sandbox and Google add-on accounts may query dates within 30 days of today, Pro the current and previous US fiscal yea… - `type` (array): Filter returned allowances. Unknown values are ignored.
If not specified, all allowances are returned.
Canonical values: cola, hardship, lqa, danger_pay, education, perdiem.
Aliases accep… - `verification_url` (boolean): Included by default: a link to the official government table for the returned location and date, for the user to confirm the figures. Pass false to omit it. ### `get_allowances_by_location` (~337 tokens) DSSR allowances by location name Returns DSSR allowances (COLA, hardship, LQA, danger pay, education, per diem) for one post in a country matched by name, case-insensitive and partial ('toky' finds Tokyo), today or on `date`. Find exact post names with get_dssr_locations_by_country or search_perdiem. Use get_allowances_by_postcode when the DSSR post code is known, get_allowances for every post in the country. Input parameters: - `country_iso_code` (string, required): ISO 3166-1 alpha-2 country code, e.g. PG for Papua New Guinea; ZZ stands for 'Other Foreign Localities', not a country. Resolve a country name to its code with get_countries (q=name). - `date`: The day the rates must be in force, YYYY-MM-DD; today when omitted.

Aliases accep… - `verification_url` (boolean): Included by default: a link to the official government table for the returned location and date, for the user to confirm the figures. Pass false to omit it. ### `get_allowances_by_postcode` (~335 tokens) DSSR allowances by location post code Returns DSSR allowances (COLA, hardship, LQA, danger pay, education, per diem) for the post identified by its five-digit DSSR post code, today or on `date`. Post codes are the State Department's own identifiers and come back in every DSSR result, so this is the most precise lookup. Use get_allowances_by_location for a name, get_allowances for the whole country. Input parameters: - `country_iso_code` (string, required): ISO 3166-1 alpha-2 country code, e.g. PG for Papua New Guinea; ZZ stands for 'Other Foreign Localities', not a country. Resolve a country name to its code with get_countries (q=name). - `date`: The day the rates must be in force, YYYY-MM-DD; today when omitted. Plan limits: Sandbox and Google add-on accounts may query dates within 30 days of today, Pro the current and previous US fiscal yea… - `postcode` (integer, required): 5-digit DSSR post code (no zero-padding) - `type` (array): Filter returned allowances. Unknown values are ignored.
If not specified, all allowances are returned.

Aliases accep… - `verification_url` (boolean): Included by default: a link to the official government table for the returned location and date, for the user to confirm the figures. Pass false to omit it. ### `search_perdiem` (~179 tokens) Search DSSR per diem by name Finds DSSR per diem by a partial, case-insensitive country or post name of at least three characters, with no country code needed. Returns lodging, M&IE and maximum per diem per matching post, today or on \`date`, with the post code for precise follow-up lookups. A name that matches nothing is a 404 error, not an empty list. Once the ISO code is known, the country tools are more precise. Input parameters: - `date`: The day the rates must be in force, YYYY-MM-DD; today when omitted. Plan limits: Sandbox and Google add-on accounts may query dates within 30 days of today, Pro the current and previous US fiscal yea… - `q` (string, required): Required case-insensitive substring of a location or country name; at least three characters after trimming. ### `get_perdiem_allowance` (~253 tokens) DSSR per diem by country Returns State Department (DSSR) per diem for every post in a country: lodging, M&IE and maximum per diem in USD per day, today or on `date`. For one post use get_perdiem_allowance_by_location or get_perdiem_allowance_by_postcode; for a place name without a country code use search_perdiem. For Department of Defense travel use get_dtmo_perdiem_oconus. Input parameters: - `country_iso_code` (string, required): ISO 3166-1 alpha-2 country code, e.g. PG for Papua New Guinea; ZZ stands for 'Other Foreign Localities', not a country. Resolve a country name to its code with get_countries (q=name). - `date`: The day the rates must be in force, YYYY-MM-DD; today when omitted. Plan limits: Sandbox and Google add-on accounts may query dates within 30 days of today, Pro the current and previous US fiscal yea… - `verification_url` (boolean): Included by default: a link to the official government table for the returned location and date, for the user to confirm the figures. Pass false to omit it. ### `get_perdiem_allowance_by_location` (~265 tokens) DSSR per diem by location name Returns DSSR per diem (lodging, M&IE and maximum per diem in USD per day) for one post in a country matched by name, case-insensitive and partial, today or on `date`. Find exact post names with get_dssr_locations_by_country or search_perdiem. Use get_perdiem_allowance for the whole country, get_perdiem_allowance_by_postcode for a known post code. Input parameters: - `country_iso_code` (string, required): ISO 3166-1 alpha-2 country code, e.g. PG for Papua New Guinea; ZZ stands for 'Other Foreign Localities', not a country. Resolve a country name to its code with get_countries (q=name). - `date`: The day the rates must be in force, YYYY-MM-DD; today when omitted. Plan limits: Sandbox and Google add-on accounts may query dates within 30 days of today, Pro the current and previous US fiscal yea… - `location` (string, required): Location name, case insensitive - `verification_url` (boolean): Included by default: a link to the official government table for the returned location and date, for the user to confirm the figures. Pass false to omit it. ### `get_perdiem_allowance_by_postcode` (~267 tokens) DSSR per diem by location post code Returns DSSR per diem (lodging, M&IE and maximum per diem in USD per day) for the post identified by its five-digit DSSR post code, today or on `date`. Every DSSR result carries the post code, so use it for follow-up lookups. Use get_perdiem_allowance_by_location for a name, get_perdiem_allowance for the whole country. Input parameters: - `country_iso_code` (string, required): ISO 3166-1 alpha-2 country code, e.g. PG for Papua New Guinea; ZZ stands for 'Other Foreign Localities', not a country. Resolve a country name to its code with get_countries (q=name). - `date`: The day the rates must be in force, YYYY-MM-DD; today when omitted.

Pass false to omit it. ### `get_dssr_locations` (~118 tokens) List DSSR posts Returns a paginated list of every DSSR post with its country, ISO code and post name; `q` filters by case-insensitive substring. `total` counts every match regardless of `offset` and `limit`. Use it to find the exact post name for the by-location tools when the country is unknown; get_dssr_locations_by_country is shorter when it is known. Returns no rates. Input parameters: - `limit` (integer) - `offset` (integer) - `q`: Search by name ### `get_countries` (~102 tokens) Find country code and posts Resolves a country name to its ISO alpha-2 code and lists the names of its DSSR posts; `q` matches the country name case-insensitively ('papua' finds PG). Use it before any tool that needs a country code. ZZ stands for Other Foreign Localities, not a country. Returns no rates. Input parameters: - `limit` (integer) - `offset` (integer) - `q`: Search by country name ### `get_country` (~124 tokens) Country by ISO code Returns one country by ISO alpha-2 code: its name, the names of its DSSR posts and State Department notes. Use get_countries to find the code from a name, and get_dssr_locations_by_country when the post codes are needed too. Returns no rates. Input parameters: - `country_iso_code` (string, required): ISO 3166-1 alpha-2 country code, e.g. PG for Papua New Guinea; ZZ stands for 'Other Foreign Localities', not a country. Resolve a country name to its code with get_countries (q=name). ### `get_dssr_locations_by_country` (~129 tokens) DSSR posts in a country Returns the DSSR posts of a country by ISO alpha-2 code, each with its name and five-digit post code (`external_id`), as needed by the by-location and by-postcode tools. Use get_countries to resolve a name to the code. Returns no rates. Input parameters: - `country_iso_code` (string, required): ISO 3166-1 alpha-2 country code, e.g. PG for Papua New Guinea; ZZ stands for 'Other Foreign Localities', not a country. Resolve a country name to its code with get_countries (q=name). ### `cola_calculator_by_postcode` (~210 tokens) DSSR COLA calculator Calculates the DSSR cost-of-living allowance (COLA) for a post: the COLA rate in percent and the annual and biweekly USD amounts for the given base salary and family size, today or on `date`. The post is identified by its five-digit DSSR post code (see get_dssr_locations_by_country). Use get_allowances for the COLA rate alone.

Allowances API is an MCP server listed in the public MCP registry as com.allowancesapi/per-diem-allowances. U.S. government per diem and overseas allowance rates from GSA, DTMO OCONUS and State DSSR tables. This page covers its hosted endpoint (https://mcp.allowancesapi.com/mcp). ### Is the Allowances API MCP server safe to use? Allowances API 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 Allowances API MCP server expose? Allowances API exposes 43 tools: get_allowances, get_allowances_by_location, get_allowances_by_postcode, search_perdiem, get_perdiem_allowance, and 38 more. Their descriptions and schemas cost roughly 8,437 tokens of context every time the server is loaded. ### Does the Allowances API MCP server require authentication? Yes. Allowances API asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything. ### Is the Allowances API MCP server still maintained? Allowances API is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced. ### What did VerifyMCP test on the Allowances API MCP server? VerifyMCP ran 13 checks on Allowances API, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out. ## Links - Remote endpoint: https://mcp.allowancesapi.com/mcp - Authorisation metadata: https://mcp.allowancesapi.com/.well-known/oauth-protected-resource/mcp - Website: https://www.allowancesapi.com/mcp-server - Changelog RSS feed: https://verifymcp.io/servers/com-allowancesapi-per-diem-allowances/mcp.xml - Changelog JSON feed: https://verifymcp.io/servers/com-allowancesapi-per-diem-allowances/mcp/changelog.json - Trust report (JSON): https://verifymcp.io/servers/com-allowancesapi-per-diem-allowances/mcp.json - HTML version of this page: https://verifymcp.io/servers/com-allowancesapi-per-diem-allowances/mcp
