AnyAPI enables AI agents to discover and call external APIs through a unified interface. Search available APIs, inspect endpoint parameters and response schemas, execute requests, and retrieve structured data from connected services without building individual integrations.
OpenCode is an open-source agent for the terminal. Remote MCP servers go in its config file and sign in through OAuth.
This guide connects AnyAPI MCP to OpenCode through MewCP, so OpenCode can use AnyAPI MCP's 10 tools, like get_api, get_balance and get_request, without your AnyAPI MCP credentials ever reaching the app.
Your AnyAPI MCP API key is stored encrypted and injected only at call time. Your agent never holds it, so it can never leak it, log it or paste it into a prompt.

Other clients
AnyAPI MCP works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact AnyAPI MCP tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
Edit ~/.config/opencode/opencode.json, or opencode.json in your project root.
Start a new chat and ask: "List the tools you can use from MewCP." You should see your connected apps.
Get the full definition of one API by API slug, including its normalized input/output JSON schemas, per-request and per-1,000-request USD pricing on every source, and nullable trailing-30-day latency p50/p95/p99 with the successful sample count. Latency percentiles describe observed successful requests; p99 is an observation, not a maximum or a client timeout guarantee. Entries with heavy:true produce large API responses.
Get the remaining wallet balance (in USD) for the AnyAPI key supplied as a Bearer token. Requires a valid AnyAPI key.
Inspect or resume a durable AnyAPI request by request_id. This reads AnyAPI's stored state and never repeats the paid provider dispatch. While status is queued or running, retryAfterSeconds gives the minimum interval between status checks.
Browse available AnyAPI APIs as lightweight summaries (id, name, category, USD pricing), optionally filtered by category. Descriptions and schemas are omitted to keep catalog responses small. Each pricing offer carries both `maxUsd` (billed per request) and `maxPer1kUsd` (the same price per 1,000 requests).
Get the exact input-aware execution price for an API, free and without a key. Nothing is charged or executed. `sku_id` and `input` identify the proposed execution; pricing resolves exactly as it does for execution, and input validation can return invalid_input without a charge. Returns maxCostUsd (the ceiling reserved), minCostUsd (the likely charge), and the base/per-item breakdown explaining why they differ. These are USD amounts for this one call, not per-1,000-request catalog comparison rates.
Read or reshape a previously paid API result without executing or paying again. `result_id` identifies the full cached result; fields/max_items/summary/jq control its presentation, including row selection and slicing large fields. Results are cached ~15 min and are private to the authenticated account; an expired id returns result_expired.
Submit a defect report to AnyAPI about wrong, empty, or malformed API data for valid input, misleading or unactionable errors, incorrect prices or schemas, or retries that failed unexpectedly. Free, never charged. `summary` is required and contains one line; optional `request_id` identifies the stored request and its upstream error body without requiring the payload in the report.
Execute an API by API slug with a normalized input payload. Every input schema is strict: unknown fields are rejected, not ignored, and field names can differ between related APIs. Inputs must conform to the endpoint's schema, not its description. Published latency p50/p95/p99 and sample counts describe observed successful requests; p99 is an observation, not a maximum or a client timeout guarantee. Requires a valid AnyAPI key as a Bearer token. Charges the USD wallet. Some failed wallet-funded requests incur processing charges passed through at cost, with no markup; the error message shows the amount charged. Results can be large. `fields` keeps selected keys, `max_items` caps returned rows, and `summary` returns an outline; these controls reduce response size without changing the charge.
Search APIs by meaning and keyword across name, slug, and description, returning matches with their descriptions but without schemas, ranked most relevant first. At least one of `query`, `category`, or `platform` is required, in any combination; `category` or `platform` without `query` enumerates that scope. `limit` caps matches (default 25, maximum 50). Each result carries a `relevance` score in (0,1] relative to the top match; a relevance floor drops weak matches, so `total` counts relevant matches before the limit. `ranking` identifies meaning-based ('semantic') or substring ('keyword') matching. Entries with heavy:true produce large API responses. Search results omit input schemas; API inputs require the endpoint's strict schema, whose field names can differ between related APIs.
Submit non-defect feedback to AnyAPI about an API you could not find in the catalog, a missing result field, confusing documentation or tool descriptions, or an improvement that would make a task easier. Free, never charged. `summary` is required and contains one line; optional `details` describes the task or suggestion.
