Capability reference

Search/list page limits above 1,000 and profile-archive limits above 100 are clamped with a notice showing the requested and applied values. Defaults are unchanged: 10 for searches and sources, 100 for countries, 25 for profile archives. Set RELIEFWEB_CLAMP_LIMITS=false to restore strict upper-bound validation. Zero, negative, and fractional limits are always rejected.

reliefweb_search_reports _tool

• Full-text query plus filters: country (ISO3), disaster ID, format, theme, language (ISO 639-1), and source shortname
• Date range filtering on source publication date (date_from/date_to) — a bare 2024-01-15 works alongside full ISO 8601
• Format is a closed set: News and Press Release, Situation Report, Map, Infographic, Analysis, Other, Assessment, Manual and Guideline, Appeal, UN Document, Evaluation and Lessons Learned — matched ignoring case, spacing, and punctuation; anything else is rejected with the list
• Raw filter object for compound conditions the named params don't cover
• Pagination via offset/limit, up to 1,000 per call (default 10)
• include_archived has no effect — reports carry no archived class, so every report is already in scope

reliefweb_get_report _tool

• Full body Markdown, all metadata, and file attachment URLs
• Use after reliefweb_search_reports to retrieve content — bodies run 10–100KB
• Over the response budget, returns a section outline instead; sections: ["body"] pulls the body back on its own
• Returns structured not_found when the ID doesn't exist

reliefweb_search_disasters _tool

• Filtering by disaster type, country, status, and GLIDE number for cross-system correlation
• Date range filtering on disaster creation date (date_from/date_to) — a bare 2024-01-15 works alongside full ISO 8601
• Status is a closed set: alert, ongoing, past, alert-archive; comma-separate for multiple, matched ignoring case, spacing, and punctuation
• alert-archive is reachable only with include_archived=true — the default preset hides it
• Pagination via offset/limit, up to 1,000 per call (default 10)
• Returns IDs for reliefweb_get_disaster and as the disaster_id filter in reliefweb_search_reports

reliefweb_get_disaster _tool

• Full description, profile overview, affected countries, and GLIDE number
• Retrieves archived disaster records as well as current ones
• Three curated lists — keyContent, appealsResponsePlans, usefulLinks — each returns only its currently-active entries; archived entries page via archive: { list: <name> }
• Major disasters run to tens of KB; over the response budget the record becomes a section outline, and sections: ["description"] or ["profileOverview"] pulls one narrative at a time
• sections and archive are alternative modes — a call supplying both is rejected
• Returns structured not_found when the ID doesn't exist

reliefweb_get_country _tool

• Situation overview text curated by OCHA editors
• Three curated lists — keyContent, appealsResponsePlans, usefulLinks — each returns only its currently-active entries; archived entries (thousands deep for a long-running crisis) page via archive: { list: <name> }
• sections and archive are alternative modes — a call supplying both is rejected
• Carries the same section-outline behavior as the other detail tools, though an active-only profile is small enough that it rarely reaches the budget
• Use reliefweb_list_countries to discover valid ISO3 codes
• Returns structured not_found for an unknown ISO3 code

reliefweb_list_countries _tool

• Optional crisis_only=true to limit to active humanitarian situations (status ongoing)
• Returns ISO3 codes, status, and canonical URLs — use ISO3 with reliefweb_get_country
• Pagination up to 1,000 entries per call (default 100)

reliefweb_search_jobs _tool

• Filtering by country, organization shortname, career category, theme, and experience level
• Returns current open postings by default; include_archived=true reaches the closed archive, far larger than the open set
• Sortable by newest posting (date.created:desc, default) or soonest closing (date.closing:asc)
• Pagination via offset/limit, up to 1,000 per call (default 10)
• Returns IDs for reliefweb_get_job

reliefweb_get_job _tool

• Full vacancy description and application instructions — neither is in search results
• Posting status, indexed / closing / last-modified dates, hiring organization, countries, career category, experience level, and job type
• Both canonical URLs (the readable alias and the node URL)
• Reaches expired postings as well as open ones
• Over the response budget, returns a section outline; sections: ["howToApply"] pulls the instructions without the whole description
• Returns structured not_found pointing back at reliefweb_search_jobs

reliefweb_search_training _tool

• Filtering by country, source, format (on-site or online), career category, and cost (free or fee-based)
• language filters the listing language; training_language filters delivery language. Summaries include cost and delivery languages when supplied by the organizer
• Date range filtering on training start date (date_start_from/date_start_to) — a bare 2024-06-01 works alongside full ISO 8601
• Scoped to training starting from now when neither date bound is given; supply either one for an explicit range, including a historical one
• include_archived=true reaches concluded listings and drops the start-from-now default, so an otherwise unbounded search reaches the whole record
• Ordered by soonest start date by default (date.start:asc, distinct from report date fields); override with sort
• Returns IDs for reliefweb_get_training

reliefweb_get_training _tool

• Full description and registration instructions — neither is in search results
• Cost class, the organizer's fee detail, and the organizer's own event URL
• Listing status, start / end / registration / indexed dates, host cities, format, type, listing and delivery languages, organizing source, and both canonical URLs
• Reaches concluded listings as well as current ones
• Over the response budget, returns a section outline; sections: ["cost", "feeInformation", "howToRegister"] pulls just the practicalities
• Returns structured not_found pointing back at reliefweb_search_training

reliefweb_list_sources _tool

• Optional filtering by name text or organization type: Government, International Organization, Non-governmental Organization, Academic and Research Institution, Media, Red Cross/Red Crescent Movement, Other
• Returns short names, types, organization URLs, and homepage URLs
• Pagination via offset/limit, up to 1,000 per call (default 10)
• Use shortname with the source filter in reliefweb_search_reports, reliefweb_search_jobs, and reliefweb_search_training

reliefweb://reports/{id} _resource

• Full report record as application/json — metadata, body text, and file URLs
• id must be digits only, exactly as search returned it
• Always returns the whole record — no section selector; use reliefweb_get_report for an oversized report

reliefweb://disasters/{id} _resource

• Disaster record as application/json — type, status, GLIDE, description, and curated content links
• id must be digits only, exactly as search returned it
• Always returns the whole record — no section selector; use reliefweb_get_disaster for an oversized disaster or to page an archive

reliefweb://countries/{iso3} _resource

• Country profile as application/json — overview, situation summary, and active response plans
• Equivalent to calling reliefweb_get_country
• iso3 must be a 3-letter ISO 3166-1 alpha-3 code

reliefweb_crisis_briefing _prompt

• Arguments: country_or_disaster required (name, ISO3 code, or GLIDE number); focus optional — situation, jobs, or full (default)
• Returns one user message instructing the agent to gather data with the ReliefWeb tools, then synthesize a briefing citing report titles and dates
• Resolves country names to ISO3 codes before filtered calls; keeps disaster-name and GLIDE searches separate

reliefweb-guide _skill

The bundled guide covers country/disaster research, opportunity evaluation, and checks before claiming that historical material is absent. MCP clients can discover and read it as a skill resource.

Features

Built on @cyanheads/mcp-ts-core: stdio and Streamable HTTP transports, pluggable auth (none / jwt / oauth), swappable storage (in-memory, filesystem, Supabase, Cloudflare KV/R2/D1), structured logging with optional OpenTelemetry tracing.

ReliefWeb-specific:

• Full coverage of all six ReliefWeb content types: reports, disasters, countries, jobs, training, and sources
• Compound filter builder supporting nested AND/OR conditions for the ReliefWeb API v2
• Vocabulary matching for report format, disaster status, and training cost normalizes case, spacing, and punctuation instead of requiring exact ReliefWeb spelling
• Date bounds reject impossible calendar dates and times locally; valid end-of-day 24:00 resolves to the next midnight
• RELIEFWEB_APP_NAME validated at startup — required by the API since November 2025
• 1,000 calls/day API quota, surfaced in each search and list tool's upstream-error recovery text

Agent-friendly output:

• Body text excluded from search results by design — agents fetch it explicitly with the matching reliefweb_get_* tool to control context budget
• Oversized records outline rather than truncate, with a section selector to retrieve exactly what's needed
• Curated-profile archives are paged rather than dropped, with honest totals and a next offset while more remain
• Typed not_found error contracts and empty-result notices that echo applied filters and suggest how to broaden

Getting started

Connect to the public hosted server with Claude Code:

claude mcp add --transport http reliefweb-mcp-server https://reliefweb.caseyjhand.com/mcp

Or run locally with your own pre-approved ReliefWeb appname:

claude mcp add reliefweb-mcp-server -e RELIEFWEB_APP_NAME=your-app-name -- npx -y @cyanheads/reliefweb-mcp-server

For other MCP clients, add this to your MCP client configuration file:

{  "mcpServers": {    "reliefweb-mcp-server": {      "command": "npx",      "args": ["-y", "@cyanheads/reliefweb-mcp-server"],      "env": {        "RELIEFWEB_APP_NAME": "your-app-name"      }    }  }}

Register an appname at ReliefWeb API. For Docker or a source build, see Running the server.

Configuration

See .env.example for the full list of optional overrides.

Running the server

Local development

Requires Bun v1.4.0 or higher (or Node.js v24+ for the built server).

git clone https://github.com/cyanheads/reliefweb-mcp-server.gitcd reliefweb-mcp-server && bun installcp .env.example .env   # set RELIEFWEB_APP_NAME

• Build and run the production version:

  sh

  # One-time buildbun run rebuild
  # Run the built serverbun run start:http# orbun run start:stdio

• Run checks and tests:

  sh

  bun run devcheck  # Lints, formats, type-checks, and morebun run test      # Runs the test suite

Docker

docker run --rm -e RELIEFWEB_APP_NAME=your-app-name -p 3010:3010 ghcr.io/cyanheads/reliefweb-mcp-server:latest

The image defaults to HTTP transport, stateless session mode, and logs to /var/log/reliefweb-mcp-server. For stdio, use docker run -i --rm -e MCP_TRANSPORT_TYPE=stdio -e RELIEFWEB_APP_NAME=your-app-name ghcr.io/cyanheads/reliefweb-mcp-server:latest. Build locally with docker build -t reliefweb-mcp-server .; OpenTelemetry peers are installed by default — add --build-arg OTEL_ENABLED=false to omit them.

Project structure

Development guide

See CLAUDE.md for development guidelines and architectural rules. The short version:

• Handlers throw, framework catches — no try/catch in tool logic
• Use ctx.log for logging, ctx.state for storage
• Register new tools and resources in the createApp() arrays
• Wrap external API calls: validate raw → normalize to domain type → return output schema; never fabricate missing fields
