- All error shapes on this page for hosted MCP, Network REST and OAuth.
Errors and what to do
Refusals are fixed sentences that tell you what to do. On MCP, HTTP 200 does not mean success: check isError. Uncertain saves are retried with identical IDs and arguments. Validation failures save nothing.
- A retry authority. A rate-limit object never authorizes a financial retry:
dispatchAuthorityis false.
Checked against release f649e1b5ac40 on my.odei.ai and ab8b603524e6 on network.odei.ai, 2026-11-06. Compare with /health.
Four shapes
| Surface | Shape |
|---|---|
| Hosted transport | HTTP status with {error, message?, field?, validation?} |
| Hosted tool refusal | HTTP 200, isError true, structuredContent{error, message?, field?, expected?, hint?, retryable?, retryAfterMs?, validation?, deprecated?, connectorUpdate?, rateLimit?, walletRateLimit?, retryAfterSeconds?, retryAt?, serviceFailure?, rpcDiagnostic?, callDiagnosis?} |
| Network REST | HTTP status with {error, message?} |
| OAuth | HTTP status with {error} |
Server codes pass through hosted MCP unchanged. Prefixes: connector_, connector_network_, connector_messages_, connector_research_, connector_profile_, connector_work_, remote_tools_, public_network_, compact_wallet_, wallet_api_. SQL, credentials, provider text and request values never appear.
What to do by status
| Status | Do |
|---|---|
| 400, 415, 422 | Fix the arguments. Use a new requestId. |
| 401 | The owner reconnects at https://my.odei.ai/connect |
| 403 | Ask the owner to review access |
| 404 | Check IDs |
| 409 | Read current state. New requestId for different arguments. |
| 413 | Shorten. Use a new requestId. |
| 429 | Wait for Retry-After or retryAfterMs. Same requestId. |
| 503 | Wait, same call |
Wallet: needs_retry means wait retryAfterMs and repeat. unknown is unresolved, not failed. reorged means never resend. retryable and retryAfterMs (up to 3600000) appear in tool errors when known.
Common codes: rate_limited 429, invalid_token 401, access_changed 401, scope_required 403, not_found 404, conflict 409, revision_conflict 409, operation_conflict 409, invalid_arguments 400, request_too_large 413, unavailable 503, request_unavailable (uncategorized tool failure, reported with HTTP 200), result_too_large (a tool error above 768 KiB).
Missing permission
Calling a tool without its scopes returns a normal HTTP 200 tool result with isError true, never a 403, so the agent sees it. No operation runs.
Fields: error insufficient_scope, state needs_permission, supported, tool, requiredScopes, missingScopes, grantedScopes, authorizationScopes, accessUrl, ownerStep, ownerUrl, message, existingAccess; wallet cases add permission. The WWW-Authenticate header and _meta mcp/www_authenticate carry the standard scope challenge.
Give the owner ownerStep and ownerUrl. A refresh or restart reuses the saved sign-in and keeps current access: the owner must remove the saved sign-in, sign in again and pick the access on the consent page. A new consent creates a separate authorization; existing access and saved requests stay. Retry the same call with the same requestId afterward.
Transport errors
| Code | Status | Meaning |
|---|---|---|
invalid_token | 401 | This connection is outdated or revoked. Reconnect at https://my.odei.ai/connect |
invalid_origin | 403 | Browser Origin not allowed |
not_found | 404 | Unknown path |
method_not_allowed | 405 | GET is refused except for one short stream |
request_too_large | 413 | Over the frame size |
json_required | 415 | Send application/json |
invalid_json, invalid_request | 400 | Malformed, or a JSON batch |
rate_limited | 429 | Over the limit, with Retry-After |
connector_unavailable | 503 | Try later |
Unknown ODEI tool. (MCP InvalidParams) means the name is not a tool or legacy wallet name. Error responses expose WWW-Authenticate, plus Retry-After on 429, to browser clients. MCP-Protocol-Version is exposed on success only.
Authority changes
Authority is checked at the read or write itself. An earlier successful read is not a lease. After a revoke, replace or expiry, the same token stops working on its next call.
| Code | Do |
|---|---|
connector_access_changed (401) | Read current state, or give the owner the reconnect link |
connector_authority_invalid (401) | Give the owner the reconnect link |
connector_scope_required (403) | Ask the owner to review access |
external_client_execution_denied | Connectors never sign or send. retryable false. |
OAuth errors
| Step | Codes |
|---|---|
| Register | invalid_redirect_uri, invalid_client_metadata, rate_limited 429, temporarily_unavailable 503 |
| Authorize | invalid_request, invalid_client, invalid_resource, invalid_redirect_uri, invalid_scope, session_changed 409, access_denied 403 (reason connection_limit or connection_history_limit), rate_limited 429, temporarily_unavailable 503 |
| Token | invalid_client 401 (Authorization header sent), invalid_resource, invalid_grant, unsupported_grant_type, rate_limited 429 |
| Revoke | invalid_client 401 with an Authorization header, rate_limited 429 |
Browser navigations get a recovery page; protocol clients get JSON. Cancel returns error=access_denied to the callback. At the connection limit the page reads Your connection limit is reached. At the history limit it reads Connection setup needs help, and the owner contacts [email protected].
Wallet
Result states are on the wallet page. Thrown errors carry {error, message, field?, expected?, hint?, retryable?}, with codes compact_wallet_*. Fix that field.
Rate limits: wallet_api_rate_limited (429) with retryAfterSeconds, retryAt, walletRateLimit{bucket, scope, limit, windowMs, retryAfterMs, retryAt}. wallet_api_rate_limit_unavailable (503). On odei_wallet_state, the wait may appear only in the message text. Chain RPC limits are separate: rateLimit with contract odei.manual-evm-rate-limit.v1, nextAction wait-and-repeat-read, dispatchAuthority false.

The exact wire form of these codes across every surface has not been tested with a write. Follow the HTTP status and message. Some connections may report work_draft_capacity_reached (409) as connector_disconnected even though they remain connected. The REST response is authoritative: this refusal means the account has reached its service or task storage limit.

In Telegram, "Your AI finished, but its reply could not be used" means nothing was acted on. Rephrase, and if it repeats, choose another connected AI. "I can read text messages only for now." means the message was a photo, file or voice.
